Leetcode Problem 73. Set Matrix Zeroes

73. Set Matrix Zeroes

Leetcode Solutions

Check if the first row and first column need to be zeroed by iterating through them separately.
Use the matrix itself to set flags on the rest of the rows and columns by iterating through the matrix starting from matrix[1][1].
If matrix[i][j] is zero, set matrix[i][0] and matrix[0][j] to zero to act as flags.
Iterate through the matrix again, using the flags to set the appropriate rows and columns to zero.
Finally, use the flags from step 1 to set the first row and column to zero if needed.
