Find the Row with the Maximum Number of 1's
You are given a non-empty grid MAT
with 'N' rows and 'M' columns, where each element is either 0 or 1. All rows are sorted in ascending order.
Your task is to determine the index of the row that contains the maximum number of 1's.
Example:
For the given grid, the row with the maximum number of 1's is at index 1 (0-indexed).
Input:
The first line contains an integer ‘T’, representing the number of test cases. Then each test case is as follows:
The first line contains two space-separated integers ‘N’ and ‘M’, representing the number of rows and columns of the grid, respectively.
The following ‘N’ lines each contain ‘M’ space-separated integers, representing the rows of the grid.
Output:
For each test case, output the index of the row with the maximum number of 1's. Print each result on a new line.
Constraints:
- 1 <= T <= 100
- 1 <= N <= 50
- 1 <= M <= 50
- 0 <= MAT[i][j] <= 1
Note: If two rows have the same number of 1's, return the one with the smaller index. The actual output does not need to be printed explicitly; it has been handled. Just implement the function to achieve the result.
Find the row with the maximum number of 1's in a grid of 0's and 1's.
Iterate through each row of the grid and count the number of 1's in each row.
Keep track of the row index with the maximum number of...read more
