Different Differences

An array aa consisting of kk integers is strictly increasing if a1<a2<⋯<aka_1 \lt a_2 \lt \dots \lt a_k. For example, the arrays [1,3,5][1, 3, 5], [1,2,3,4][1, 2, 3, 4], [3,5,6][3, 5, 6] are strictly increasing; the arrays [2,2][2, 2], [3,7,5][3, 7, 5], [7,4,3][7, 4, 3], [1,2,2,3][1, 2, 2, 3] are not.

For a strictly increasing array aa of kk elements, let's denote the characteristic as the number of different elements in the array [a2−a1,a3−a2,…,ak−ak−1][a_2 - a_1, a_3 - a_2, \dots, a_k - a_{k-1}]. For example, the characteristic of the array [1,3,4,7,8][1, 3, 4, 7, 8] is 33 since the array [2,1,3,1][2, 1, 3, 1] contains 33 different elements: 22, 11 and 33.

You are given two integers kk and nn (k≤nk \le n). Construct an increasing array of kk integers from 11 to nn with maximum possible characteristic.

Input

The first line contains one integer tt (1≤t≤8191 \le t \le 819) — the number of test cases.

Each test case consists of one line containing two integers kk and nn (2≤k≤n≤402 \le k \le n \le 40).

Output

For each test case, print kk integers — the elements of the strictly increasing array aa with the maximum possible characteristic. If there are multiple answers, print any of them.
