好多数学题,这道题就当放松一下心情吧

#include<iostream>

using namespace std;

int main(){
    int n;
    while(cin >> n){
        int cnt = 0, num;
        for(int i = 0; i < n; i ++){
            cin >>num;
            if(num % 2 == 0) cnt ++;
            else cnt --;
        }
        if(cnt > 0) cout << "NO" << endl;
        else cout << "YES" << endl;
    }
    return 0;
}
