You are given an array Arr consisting of n integers. You need to find the equilibrium index of the array. An index is considered as equilibrium index if the sum of elements to the left of that index is equal to the sum of elements to the right of it.

Note:

The array follows 0-based indexing, so you need to return the 0- based index of the element. If there are multiple indices which satisfy the given condition, then return the left-most index. If no such index is present in the array, return -1.
