类似求众数

#include <iostream>
#include <algorithm>

using namespace std;

const int N = 1010;
int cnt[N];

int main(){
    string str;

    cin>>str;

    int max_cnt = -1;

    for (int i = 0;i<str.size();i++){
        cnt[str[i]]++;
        max_cnt=max(max_cnt,cnt[str[i]]);
    }
    sort(str.begin(),str.end());

    for (int i = 0;i<str.size();i++){
        if (cnt[str[i]] == max_cnt){
            cout<<str[i]<<endl;
            break;
        }
    }

    return 0;
