##### Submissions: 2475   Accuracy: 24.42%   Difficulty: Easy   Marks: 2

Given an array of elements. The task is to calculate the cumulative frequency of each element of the array.

Input:
The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. Each test case consists of two lines. First line of each test case contains an integer N and the second line contains N space separated array elements.

Output:
For each test case, print the space separated cumulative frequency of each element of sorted array in new line.

Constraints:
1<=T<=100
1<=N<=105

1<=A[i]<=105

Example:
Input:

2
6
1 2 2 1 3 4
6
1 2 1 2 1 2

Output:
2 4 5 6
3 6

Explanation:

```Input : arr[] = [1, 3, 2, 1, 2, 4]
Output :1->2
2->4
3->5
4->6

Input : arr[] = [1, 2, 1, 2, 1, 2]
Output :1->3
2->6```
