Given a 2D list of size `m * n`. Your task is to find the sum of minimum value in each row.
For Example:
```python
[
  [1, 2, 3, 4, 5],       # minimum value of row is 1
  [5, 6, 7, 8, 9],       # minimum value of row is 5
  [20, 21, 34, 56, 100]  # minimum value of row is 20
]
```
So, the function should return `26` because sum of minimums is as `1 + 5 + 20 = 26`
