Now for query ‘C(x, y)’ just swap the value of cols with cols.

Now for query ‘R(x, y)’ just swap the value of rows with rows.

Create another auxiliary array cols and fill it with values 0 to n-1 sequentially.

Create an auxiliary array rows and fill it with values 0 to m-1 sequentially.

Here we are given that elements in matrix are filled from 1 to mxn sequentially in row major order, so we will take advantage of this given scenario and can solve this problem. But this approach may have time complexity of q*O(m) or q*O(n) where ‘q’ is number of queries and auxiliary space required O(m*n).Īn efficient approach for this problem requires little bit mathematical observation.

Recommended: Please try your approach on first, before moving on to the solution.Ī simple solution for this problem is to finish all the queries manually, that means when we have to swap the rows just swap the elements of x’th row and y’th row and similarly for column swamping. Note that the given matrix is stored as a typical 2D array with indexes start from 0, but values of x and y start from 1. P(x, y): prints the element at x-th row and y-th column where x varies from 1 to m and y varies from 1 to n.C(x, y): swaps the x-th and y-th columns of M where x and y vary from 1 to n.R(x, y): swaps the x-th and y-th rows of M where x and y vary from 1 to m.The task is to process a list of queries manipulating M such that every query is one of the following three. It is initially filled with integers from 1 to m x n sequentially in a row major order.
