点点我吧

代码：

#include <bits/stdc++.h>
using namespace std;
string ZS_D_n(int q, int s){ //十进制转N进制(整数) 
    vector<char> ve;
    do {
        if(q > 10 && s % q > 9){
            ve.push_back('A' + s % q - 10);
        } else {
            ve.push_back(s % q + '0');
        }
        s /= q;
    } while(s);
    reverse(ve.begin(),ve.end()); //反转数组
    string sum;
    for(int i = 0;i < ve.size();i++){
        sum += ve[i];
    }
    return sum;
}
int main(){
    int n;
    cin >> n;
    string s = ZS_D_n(8,n);
    int l = 0,r = s.size() - 1;
    while(l <= r){
        if(s[l] != s[r]){
            cout << "NO";
            return 0;
        } 
        l++,r--;
    }
    cout << "YES";
	return 0;
