This code is showing MLE. Why?!!!!!!
1.#include<bits/stdc++.h>
using namespace std;
int main(void) { string a,b,c;
scanf("%s %s %s",&a,&b,&c);
a=a+b;
sort(a.begin(),a.end());
sort(c.begin(),c.end());
if(a==c)
printf("YES");
else
printf("NO");
return 0;
}
but when I using this code below it was accepted.What is the fact here between scanf and cin or else?
2.#include<bits/stdc++.h>
using namespace std;
int main(void) { string a,b,c;
cin>>a>>b>>c;
a+=b;
sort(a.begin(),a.end());
sort(c.begin(),c.end());
if(a==c)
cout<<"YES";
else
cout<<"NO";
return 0;
}
