Sum of Minimums!

Given an 2D list of size m * n. Your task is to find the sum of minimum value in each row.

Examples

[
  [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

Note: You will be always given non-empty list containing Positive values.
