[Solution] Cross Swapping solution codeforces

Cross Swapping solution codeforces – You are given a square matrix 𝐴A of size 𝑛×𝑛n×n whose elements are integers. We will denote the element on the intersection of the 𝑖i-th row and the 𝑗j-th column as 𝐴𝑖,𝑗Ai,j. [Solution] Cross Swapping solution codeforces You can perform operations on the matrix. In each operation, you can choose an integer 𝑘k, then for each index 𝑖i (1≤𝑖≤𝑛1≤i≤n), … Read more
