Given an array of positive integers. Your task is 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**, size of array. The second line of each test case contains array elements.

**Output:**

Print the 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
