CF1458C Latin Square

You are given a square matrix of size $ n $ . Every row and every column of this matrix is a permutation of $ 1 $ , $ 2 $ , $ \ldots $ , $ n $ . Let $ a_{i, j} $ be the element at the intersection of $ i $ -th row and $ j $ -th column for every $ 1 \leq i, j \leq n $ . Rows are numbered $ 1, \ldots, n $ top to bottom, and columns are numbered $ 1, \ldots, n $ left to right. There are six types of operations: - R: cyclically shift all columns to the right, formally, set the value of each $ a_{i, j} $ to $ a_{i, ((j - 2)\bmod n) + 1} $ ; - L: cyclically shift all columns to the left, formally, set the value of each $ a_{i, j} $ to $ a_{i, (j\bmod n) + 1} $ ; - D: cyclically shift all rows down, formally, set the value of each $ a_{i, j} $ to $ a_{((i - 2)\bmod n) + 1, j} $ ; - U: cyclically shift all rows up, formally, set the value of each $ a_{i, j} $ to $ a_{(i\bmod n) + 1, j} $ ; - I: replace the permutation read left to right in each row with its inverse. - C: replace the permutation read top to bottom in each column with its inverse. Inverse of a permutation $ p_1 $ , $ p_2 $ , $ \ldots $ , $ p_n $ is a permutation $ q_1 $ , $ q_2 $ , $ \ldots $ , $ q_n $ , such that $ p_{q_i} = i $ for every $ 1 \leq i \leq n $ .One can see that after any sequence of operations every row and every column of the matrix will still be a permutation of $ 1, 2, \ldots, n $ . Given the initial matrix description, you should process $ m $ operations and output the final matrix.
