大小写判断+空格判断+开辟两个新字符串

#include<bits/stdc++.h>
using namespace std;
int main(){
    string a,b,a1 = "",b1 = "";
    getline(cin,a); getline(cin,b);
    int l1 = a.size(),l2 = b.size();
    for(int i = 0;i < l1;i++){
        if(a[i] == ' ') continue;
        else if(a[i] >= 'a' && a[i] <= 'z') a1 += a[i] - 32;
        else a1 += a[i];
    }
    for(int i = 0;i < l2;i++){
        if(b[i] == ' ') continue;
        else if(b[i] >= 'a' && b[i] <= 'z') b1 += b[i] - 32;
        else b1 += b[i];
    }
    if(a1 == b1) cout << "YES";
    else cout << "NO";
    return 0;
}
