Max and Min Zero Rows in Matrix of Sorted Rows

Challenge

Given a 2D array where the rows are sorted and contain only 0 and 1. Return the index of the row with the biggest amount of zeroes, and the index of the row with the biggest amount of zeroes.

Approach & Efficiency

Loop through rows of the matrix and perform binary search on individual rows to get the index of the first 1 to occur.

Analysis:

Time: O(m * log(n)), m is the number of rows and n is the length of the rows Space: O(1)
