Fixed Prefix Permutations

You are given nn permutations a1,a2,,ana_1, a_2, \dots, a_n, each of length mm. Recall that a permutation of length mm is a sequence of mm distinct integers from 11 to mm.

Let the beauty of a permutation p1,p2,,pmp_1, p_2, \dots, p_m be the largest kk such that p1=1,p2=2,,pk=kp_1 = 1, p_2 = 2, \dots, p_k = k. If p11p_1 \neq 1, then the beauty is 00.

The product of two permutations pqp \cdot q is a permutation rr such that rj=qpjr_j = q_{p_j}.

For each ii from 11 to nn, print the largest beauty of a permutation aiaja_i \cdot a_j over all jj from 11 to nn (possibly, i=ji = j).

Input

The first line contains a single integer tt (1t1041 \le t \le 10^4) — the number of testcases.

The first line of each testcase contains two integers nn and mm (1n51041 \le n \le 5 \cdot 10^4; 1m101 \le m \le 10) — the number of permutations and the length of each permutation.

The ii-th of the next nn lines contains a permutation aia_i — mm distinct integers from 11 to mm.

The sum of nn doesn't exceed 51045 \cdot 10^4 over all testcases.

Output

For each testcase, print nn integers. The ii-th value should be equal to the largest beauty of a permutation aiaja_i \cdot a_j over all jj (1jn1 \le j \le n).
