( 19840 ) D Permutation Transformation PROGRAMMING dfs and similar divide and conquer implementation

B'A permutation -- is a sequence of length n integers from 1 to n , in which all the numbers occur exactly once. For example, [1] , [3, 5, 2, 1, 4] , [1, 3, 2] -- permutations, and [2, 3, 2] , [4, 3, 1] , [0] -- no. Polycarp was recently gifted a permutation a[1 ... n] of length n . Polycarp likes trees more than permutations, so he wants to transform permutation a into a rooted binary tree. He transforms an array of different integers into a tree as follows: For example, if he builds a tree by permutation a=[3, 5, 2, 1, 4] , then the root will be the element a_2=5 , and the left subtree will be the tree that will be built for the subarray a[1 ... 1] = [3] , and the right one -- for the subarray a[3 ... 5] = [2, 1, 4] . As a result, the following tree will be built: Another example: let the permutation be a=[1, 3, 2, 7, 5, 6, 4] . In this case, the tree looks like this: Let us denote by d_v the depth of the vertex a_v , that is, the number of edges on the path from the root to the vertex numbered a_v . Note that the root depth is zero. Given the permutation a , for each vertex, find the value of d_v . The first line contains one integer t ( 1 <= t <= 100 ) -- the number of test cases. Then t test cases follow. The first line of each test case contains an integer n ( 1 <= n <= 100 ) -- the length of the permutation. This is followed by n numbers a_1, a_2, ldots, a_n -- permutation a . For each test case, output n values -- d_1, d_2, ldots, d_n . '...
