Output

Your program should output a test case where Maija's solution fails.

Constraints (of your output)

  • 1 \le n \le 10^5
  • 1 \le a_i \le n

Maija's code

#include <bits/stdc++.h>

using namespace std;

    for(int &i : a) cin >> i;

    vector<bool> visited(n, 0);
    for(int i=0; i<n; i++){
        if(visited[i]) continue;
        if(a[i]*a[i] < n){
            vector<int> count(a[i], 0);
            for(int j=i, k=0; j<n; j++, k=(k+1)%a[i]){
                count[k] += a[i] == a[j];
