CF1792D.Fixed Prefix Permutations
Fixed Prefix Permutations
You are given permutations , each of length . Recall that a permutation of length is a sequence of distinct integers from to .
Let the beauty of a permutation be the largest such that . If , then the beauty is .
The product of two permutations is a permutation such that .
For each from to , print the largest beauty of a permutation over all from to (possibly, ).
Input
The first line contains a single integer () — the number of testcases.
The first line of each testcase contains two integers and (; ) — the number of permutations and the length of each permutation.
The -th of the next lines contains a permutation — distinct integers from to .
The sum of doesn't exceed over all testcases.
Output
For each testcase, print integers. The -th value should be equal to the largest beauty of a permutation over all ().
