c/c++求解这个编程问题

这是我写的代码，结果完全不正确，求解答，我循环输出b数组的时候数据也不对

下面的代码结果对的：

#include <iostream>
using namespace std;

int main()
{
    int candidates[6] = {0}; 
    int n = 0;
    cin >> n;
    int x;
    for (int i=1; i <=n; i++) {
        cin >> x;   
        candidates[x]++;   // 投的谁的票， 谁的票数加1
    }
    int max=0;
    int maxIndex=0;
    for (int i=1; i <= 5; i++) {
        if (max <= candidates[i]) {
            max = candidates[i];
            maxIndex = i;
        }
    }
    cout << "winner: " << maxIndex << " with " << max << " votes" << endl;
    return 0;
}

运行结果：
10
1 1 1 1 1 2 2 3 4 5
winner: 1 with 5 votes
