Given an array, we need to find that element whose value is equal to that of its index value.

**Input:**

The first line of input contains an integer T denoting the number of test cases.

The first line of each test case is N,N is the size of array.

The second line of each test case contains N input A[].

**Output:**

Print that element whose value is equal to index value. Print "Not Found" when index value does not match with value.

**Note**: There can be more than one element in the array which have same value as their index. You need to print every such element's index separated by a single space. Follows 1-based indexing of the array.

**Constraints:**

1 ≤ T ≤ 30

1 ≤ N ≤ 50

1 ≤ A[i] ≤ 1000

**Example:**
