An operation [a,b] add by one for all 0 <= i < a and 0 <= j < b.

So the number of maximum integers in the matrix after performing all the operations or the integers in matrix that get added by 1 by all operations are the integers that in *0 <=i<min_a* and *0<=i<min_b* or **min_a * min_b**

```
def maxCount(self, m, n, ops):
"""
:type m: int
:type n: int
:type ops: List[List[int]]
:rtype: int
"""
if not ops:
return m*n
return min(op[0] for op in ops)*min(op[1] for op in ops)
```
