Rearrange an array with O(1)Space

//Given an array arr[] of size N where every element is in the range from 0 to n-1. Rearrange the given array so that arr[i] becomes arr[arr[i]].
//N = 5 arr[] = {4,0,2,1,3} Output: 3 4 2 0 1

void arrange(long long arr[], int n) {
    // Your code here
    for (int i = 0; i < n; i++) 
            arr[i] += (arr[arr[i]] % n) * n; 
        for (int i = 0; i < n; i++) 
            arr[i] /= n;
