This is an interactive problem.Anton and Harris are playing a game to decide which of them is the king of problemsetting.There are three piles of stones, initially containing $$$a$$$, $$$b$$$, and $$$c$$$ stones, where $$$a$$$, $$$b$$$, and $$$c$$$ are distinct positive integers. On each turn of the game, the following sequence of events takes place: The first player chooses a positive integer $$$y$$$ and provides it to the second player. The second player adds $$$y$$$ stones to one of the piles, with the condition that he cannot choose the same pile in two consecutive turns. The second player loses if, at any point, two of the piles contain the same number of stones. The first player loses if $$$1000$$$ turns have passed without the second player losing.Feeling confident in his skills, Anton decided to let Harris choose whether he wants to go first or second. Help Harris defeat Anton and become the king of problemsetting!

NoteIn the sample input, the piles initially have $$$5$$$, $$$2$$$, and $$$6$$$ stones. Harris decides to go first and provides the number $$$2$$$ to Anton. Anton adds $$$2$$$ stones to the third pile, which results in $$$5$$$, $$$2$$$, and $$$8$$$.In the next turn, Harris chooses $$$3$$$. Note that Anton cannot add the stones to the third pile since he chose the third pile in the previous turn. Anton realizes that he has no valid moves left and reluctantly recognizes Harris as the king.

NoteIn the sample input, the piles initially have $$$5$$$, $$$2$$$, and $$$6$$$ stones. Harris decides to go first and provides the number $$$2$$$ to Anton. Anton adds $$$2$$$ stones to the third pile, which results in $$$5$$$, $$$2$$$, and $$$8$$$.In the next turn, Harris chooses $$$3$$$. Note that Anton cannot add the stones to the third pile since he chose the third pile in the previous turn. Anton realizes that he has no valid moves left and reluctantly recognizes Harris as the king.

You are policeman and you are playing a game with Slavik. The game is turn-based and each turn consists of two phases. During the first phase you make your move and during the second phase Slavik makes his move.There are $$$n$$$ doors, the $$$i$$$-th door initially has durability equal to $$$a_i$$$.During your move you can try to break one of the doors. If you choose door $$$i$$$ and its current durability is $$$b_i$$$ then you reduce its durability to $$$max(0, b_i - x)$$$ (the value $$$x$$$ is given).During Slavik's move he tries to repair one of the doors. If he chooses door $$$i$$$ and its current durability is $$$b_i$$$ then he increases its durability to $$$b_i + y$$$ (the value $$$y$$$ is given). Slavik cannot repair doors with current durability equal to $$$0$$$.The game lasts $$$10^{100}$$$ turns. If some player cannot make his move then he has to skip it.Your goal is to maximize the number of doors with durability equal to $$$0$$$ at the end of the game. You can assume that Slavik wants to minimize the number of such doors. What is the number of such doors in the end if you both play optimally?

You are policeman and you are playing a game with Slavik. The game is turn-based and each turn consists of two phases. During the first phase you make your move and during the second phase Slavik makes his move.There are $$$n$$$ doors, the $$$i$$$-th door initially has durability equal to $$$a_i$$$.During your move you can try to break one of the doors. If you choose door $$$i$$$ and its current durability is $$$b_i$$$ then you reduce its durability to $$$max(0, b_i - x)$$$ (the value $$$x$$$ is given).During Slavik's move he tries to repair one of the doors. If he chooses door $$$i$$$ and its current durability is $$$b_i$$$ then he increases its durability to $$$b_i + y$$$ (the value $$$y$$$ is given). Slavik cannot repair doors with current durability equal to $$$0$$$.The game lasts $$$10^{100}$$$ turns. If some player cannot make his move then he has to skip it.Your goal is to maximize the number of doors with durability equal to $$$0$$$ at the end of the game. You can assume that Slavik wants to minimize the number of such doors. What is the number of such doors in the end if you both play optimally?

You are policeman and you are playing a game with Slavik. The game is turn-based and each turn consists of two phases. During the first phase you make your move and during the second phase Slavik makes his move.There are $$$n$$$ doors, the $$$i$$$-th door initially has durability equal to $$$a_i$$$.During your move you can try to break one of the doors. If you choose door $$$i$$$ and its current durability is $$$b_i$$$ then you reduce its durability to $$$max(0, b_i - x)$$$ (the value $$$x$$$ is given).During Slavik's move he tries to repair one of the doors. If he chooses door $$$i$$$ and its current durability is $$$b_i$$$ then he increases its durability to $$$b_i + y$$$ (the value $$$y$$$ is given). Slavik cannot repair doors with current durability equal to $$$0$$$.The game lasts $$$10^{100}$$$ turns. If some player cannot make his move then he has to skip it.Your goal is to maximize the number of doors with durability equal to $$$0$$$ at the end of the game. You can assume that Slavik wants to minimize the number of such doors. What is the number of such doors in the end if you both play optimally?

You are policeman and you are playing a game with Slavik. The game is turn-based and each turn consists of two phases. During the first phase you make your move and during the second phase Slavik makes his move.There are $$$n$$$ doors, the $$$i$$$-th door initially has durability equal to $$$a_i$$$.During your move you can try to break one of the doors. If you choose door $$$i$$$ and its current durability is $$$b_i$$$ then you reduce its durability to $$$max(0, b_i - x)$$$ (the value $$$x$$$ is given).During Slavik's move he tries to repair one of the doors. If he chooses door $$$i$$$ and its current durability is $$$b_i$$$ then he increases its durability to $$$b_i + y$$$ (the value $$$y$$$ is given). Slavik cannot repair doors with current durability equal to $$$0$$$.The game lasts $$$10^{100}$$$ turns. If some player cannot make his move then he has to skip it.Your goal is to maximize the number of doors with durability equal to $$$0$$$ at the end of the game. You can assume that Slavik wants to minimize the number of such doors. What is the number of such doors in the end if you both play optimally?

You are policeman and you are playing a game with Slavik. The game is turn-based and each turn consists of two phases. During the first phase you make your move and during the second phase Slavik makes his move.There are $$$n$$$ doors, the $$$i$$$-th door initially has durability equal to $$$a_i$$$.During your move you can try to break one of the doors. If you choose door $$$i$$$ and its current durability is $$$b_i$$$ then you reduce its durability to $$$max(0, b_i - x)$$$ (the value $$$x$$$ is given).During Slavik's move he tries to repair one of the doors. If he chooses door $$$i$$$ and its current durability is $$$b_i$$$ then he increases its durability to $$$b_i + y$$$ (the value $$$y$$$ is given). Slavik cannot repair doors with current durability equal to $$$0$$$.The game lasts $$$10^{100}$$$ turns. If some player cannot make his move then he has to skip it.Your goal is to maximize the number of doors with durability equal to $$$0$$$ at the end of the game.

If you choose door $$$i$$$ and its current durability is $$$b_i$$$ then you reduce its durability to $$$max(0, b_i - x)$$$ (the value $$$x$$$ is given).During Slavik's move he tries to repair one of the doors. If he chooses door $$$i$$$ and its current durability is $$$b_i$$$ then he increases its durability to $$$b_i + y$$$ (the value $$$y$$$ is given). Slavik cannot repair doors with current durability equal to $$$0$$$.The game lasts $$$10^{100}$$$ turns. If some player cannot make his move then he has to skip it.Your goal is to maximize the number of doors with durability equal to $$$0$$$ at the end of the game. You can assume that Slavik wants to minimize the number of such doors. What is the number of such doors in the end if you both play optimally?

Kolya is going to make fresh orange juice. He has n oranges of sizes a1, a2, ..., an. Kolya will put them in the juicer in the fixed order, starting with orange of size a1, then orange of size a2 and so on. To be put in the juicer the orange must have size not exceeding b, so if Kolya sees an orange that is strictly greater he throws it away and continues with the next one.The juicer has a special section to collect waste. It overflows if Kolya squeezes oranges of the total size strictly greater than d. When it happens Kolya empties the waste section (even if there are no more oranges) and continues to squeeze the juice. How many times will he have to empty the waste section?

Kolya is going to make fresh orange juice. He has n oranges of sizes a1, a2, ..., an. Kolya will put them in the juicer in the fixed order, starting with orange of size a1, then orange of size a2 and so on. To be put in the juicer the orange must have size not exceeding b, so if Kolya sees an orange that is strictly greater he throws it away and continues with the next one.The juicer has a special section to collect waste. It overflows if Kolya squeezes oranges of the total size strictly greater than d. When it happens Kolya empties the waste section (even if there are no more oranges) and continues to squeeze the juice. How many times will he have to empty the waste section?

Last year Bob earned by selling memory sticks. During each of n days of his work one of the two following events took place: A customer came to Bob and asked to sell him a 2x MB memory stick. If Bob had such a stick, he sold it and got 2x berllars. Bob won some programming competition and got a 2x MB memory stick as a prize. Bob could choose whether to present this memory stick to one of his friends, or keep it. Bob never kept more than one memory stick, as he feared to mix up their capacities, and deceive a customer unintentionally. It is also known that for each memory stick capacity there was at most one customer, who wanted to buy that memory stick.

Last year Bob earned by selling memory sticks. During each of n days of his work one of the two following events took place: A customer came to Bob and asked to sell him a 2x MB memory stick. If Bob had such a stick, he sold it and got 2x berllars. Bob won some programming competition and got a 2x MB memory stick as a prize. Bob could choose whether to present this memory stick to one of his friends, or keep it. Bob never kept more than one memory stick, as he feared to mix up their capacities, and deceive a customer unintentionally. It is also known that for each memory stick capacity there was at most one customer, who wanted to buy that memory stick. Now, knowing all the customers' demands and all the prizes won at programming competitions during the last n days, Bob wants to know, how much money he could have earned, if he had acted optimally.

Last year Bob earned by selling memory sticks. During each of n days of his work one of the two following events took place: A customer came to Bob and asked to sell him a 2x MB memory stick. If Bob had such a stick, he sold it and got 2x berllars. Bob won some programming competition and got a 2x MB memory stick as a prize. Bob could choose whether to present this memory stick to one of his friends, or keep it. Bob never kept more than one memory stick, as he feared to mix up their capacities, and deceive a customer unintentionally. It is also known that for each memory stick capacity there was at most one customer, who wanted to buy that memory stick. Now, knowing all the customers' demands and all the prizes won at programming competitions during the last n days, Bob wants to know, how much money he could have earned, if he had acted optimally.

Last year Bob earned by selling memory sticks. During each of n days of his work one of the two following events took place: A customer came to Bob and asked to sell him a 2x MB memory stick. If Bob had such a stick, he sold it and got 2x berllars. Bob won some programming competition and got a 2x MB memory stick as a prize. Bob could choose whether to present this memory stick to one of his friends, or keep it. Bob never kept more than one memory stick, as he feared to mix up their capacities, and deceive a customer unintentionally. It is also known that for each memory stick capacity there was at most one customer, who wanted to buy that memory stick. Now, knowing all the customers' demands and all the prizes won at programming competitions during the last n days, Bob wants to know, how much money he could have earned, if he had acted optimally.

standard input
[ "greedy", "strings" ]
c01fc2cb6efc7eef290be12015f8d920
The first line of the input contains one integer $$$n$$$ ($$$2 \le n \le 2 \cdot 10^5$$$) — the length of $$$s$$$. The second line of the input contains exactly $$$n$$$ lowercase Latin letters — the string $$$s$$$.
1,200
Print one string — the smallest possible lexicographically string that can be obtained by removing at most one character from the string $$$s$$$.
