求问
问一下,为什么循环里i和j从一开始不正确呢?
#include<iostream>
using namespace std;
int main(){
int n;
cin>>n;
for(int i=2;i<n;i++){
for(int j=2;j<n;j++){
if(i+j==n){
if(i%2==0&&j%2==0)cout<<"YES, you can divide the watermelon into two even parts."<<endl;
return 0;
}
}
}
cout<<"NO, you can't divide the watermelon into two even parts."<<endl;
}
}
