The problem "Set Matrix Rows and Columns to Zeroes" involves updating a matrix such that if an element is zero, its entire row and column are set to zero. This can be achieved using two approaches: using two auxiliary arrays or by modifying the first row and column of the matrix itself. The naive approach marks rows and columns using additional arrays, while the expected approach modifies the matrix in-place to optimize space. Both methods have a time complexity of O(n*m), with the latter approach reducing space complexity to O(1).
