Description
Let S = S1 s2...s2n is a well-formed string of parentheses. S can is encoded in different ways:
QBy an integer sequence p = p1 p2...pn where pi are the number of left parentheses before the ith right parenthesis in S (P -sequence).
QBy an integer sequence W = W1 W2...wn where for each right parenthesis, say a in S, we associate an integer which is the Number of right parentheses counting from the matched left parenthesis of a up to a. (W-sequence).
Following is an example of the above encodings:
S ((((() () () ()))
P-sequence 4 5 6666
W-sequence 1 1 1456
Write a program to convert p-sequence of a well-formed string to the w-sequence of the same string.
Input
The first line of the input contains a single integer t (1 <= t <=), the number of test cases, followed by the Put data for each test case. The first line of all test case was an integer n (1 <= n <=), and the second line is the p-sequence of a well-for Med string. It contains n positive integers, separated with blanks, representing the p-sequence.
Output
The output file consists of exactly t lines corresponding to test cases. For each test case, the output line should contain n integers describing the w-sequence of the string corresponding to its Given p-sequence.
