Given an array **Arr** of **N** positive integers. Your task is to find the elements whose value is equal to that of its index value.

**Example 1:**

**Input:
**N = 5
Arr[] = {15, 2, 45, 12, 7}
**Output:** 2
**Explanation:** Only Arr[2] = 2 exists here.

**Example 2:**

**Input:**
N = 1
Arr[] = {1}
**Output:** 1
**Explanation:** Here Arr[1] = 1 exists.

**Your Task: **

You don't need to read input or print anything. Your task is to complete the function **valueEqualToIndex()** which takes the array of integers **arr[]**** **and** n **as parameters and returns an array of indices where the given conditions are satified. When there is not such element exists then return an empty array of length 0.

**Expected Time Complexity:** O(N)

**Expected Auxiliary Space:** O(1)

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

**Constraints:**

1 ≤ N ≤ 10^{5}

1 ≤ Arr[i] ≤ 10^{6}
