C. column swapping
WebHere we will do swapping of column in a 2D array. You are given a matrix M or r rows and c columns. You need to swap the first column with the last column. Example: Input: 3 4 1 2 3 4 4 3 2 1 6 7 8 9 Output: 4 2 3 1 1 3 2 4 9 7 8 6 Your Task: Since this is a function problem, you don't need to take any input. WebC. Column Swapping. 题意：给定若干数组 \mathcal{A_1,A_2...A_n} ，每个数组恰有 m 个元素。. 问：能否选择两个位置 x,y ，对于每个数组 \mathcal{A_i} 交换 \mathcal{A_{i,x},A_{i,y}} ，使得交换后，所有数组保持有序。. 如果可以，输出这样的位置。否则输出 -1 。. 分析：如果所有数组原先就有序，输出 1\ 1 即可。
