Welcome to the daily solving of our PROBLEM OF THE DAY with Siddharth Hazra. We will discuss the entire problem step-by-step and work towards developing an optimized solution. This will not only help you brush up on your concepts of Matrix but will also help you build up problem-solving skills.
In this problem, we are given, a boolean matrix of size RxC where each cell contains either 0 or 1, Our task is to modify it such that if a matrix cell matrix[i][j] is 1 then all the cells in its ith row and jth column will become 1.
Example :
Input:
R = 2, C = 2
matrix[][] = {{1, 0},
{0, 0}}
Output:
1 1
1 0
Explanation:
Only cell that has 1 is at (0,0) so all cells in row 0 are modified to 1 and all cells in column 0 are modified to 1.
Give the problem a try before going through the video. All the best!!!
