# Find maximum element of each row in a matrix

Given a matrix, the task is to find the maximum element of each row.

Examples:

```Input :  [1, 2, 3]
[1, 4, 9]
[76, 34, 21]

Output :
3
9
76

Input : [1, 2, 3, 21]
[12, 1, 65, 9]
[1, 56, 34, 2]
Output :
21
65
56
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Approach : Approach is very simple. The idea is to run the loop for no_of_rows. Check each element inside the row and find for the maximum element. Finally, print the element.

Below is the implementation :
