p02802 AtCoder Beginner Contest 151 - Welcome to AtCoder
Takahashi participated in a contest on AtCoder. The contest had N problems. Takahashi made M submissions during the contest. The i-th submission was made for the p_i-th problem and received the verdict S_i (`AC` or `WA`). The number of Takahashi's correct answers is the number of problems on which he received an `AC` once or more. The number of Takahashi's penalties is the sum of the following count for the problems on which he received an `AC` once or more: the number of `WA`s received before receiving an `AC` for the first time on that problem. Find the numbers of Takahashi's correct answers and penalties. Constraints * N, M, and p_i are integers. * 1 \leq N \leq 10^5 * 0 \leq M \leq 10^5 * 1 \leq p_i \leq N * S_i is `AC` or `WA`. Input Input is given from Standard Input in the following format: N M p_1 S_1 : p_M S_M Output Print the number of Takahashi's correct answers and the number of Takahashi's penalties. Examples Input 2 5 1 WA 1 AC 2 WA 2 AC 2 WA Output 2 2 Input 100000 3 7777 AC 7777 AC 7777 AC Output 1 0 Input 6 0 Output 0 0

Takahashi participated in a contest on AtCoder. The contest had N problems. Takahashi made M submissions during the contest. The i-th submission was made for the p_i-th problem and received the verdict S_i (`AC` or `WA`). The number of Takahashi's correct answers is the number of problems on which he received an `AC` once or more. The number of Takahashi's penalties is the sum of the following count for the problems on which he received an `AC` once or more: the number of `WA`s received before receiving an `AC` for the first time on that problem. Find the numbers of Takahashi's correct answers and penalties. Constraints * N, M, and p_i are integers. * 1 \leq N \leq 10^5 * 0 \leq M \leq 10^5 * 1 \leq p_i \leq N * S_i is `AC` or `WA`.

p02802 AtCoder Beginner Contest 151 - Welcome to AtCoder
Takahashi participated in a contest on AtCoder. The contest had N problems. Takahashi made M submissions during the contest. The i-th submission was made for the p_i-th problem and received the verdict S_i (`AC` or `WA`). The number of Takahashi's correct answers is the number of problems on which he received an `AC` once or more. The number of Takahashi's penalties is the sum of the following count for the problems on which he received an `AC` once or more: the number of `WA`s received before receiving an `AC` for the first time on that problem. Find the numbers of Takahashi's correct answers and penalties. Constraints * N, M, and p_i are integers. * 1 \leq N \leq 10^5 * 0 \leq M \leq 10^5 * 1 \leq p_i \leq N * S_i is `AC` or `WA`. Input Input is given from Standard Input in the following format: N M p_1 S_1 : p_M S_M Output Print the number of Takahashi's correct answers and the number of Takahashi's penalties. Examples Input 2 5 1 WA 1 AC 2 WA 2 AC 2 WA Output 2 2 Input 100000 3 7777 AC 7777 AC 7777 AC Output 1 0 Input 6 0 Output 0 0
