Why all test case are not passed

#1

Only one test case is passed ,i think my logic is correct ,please tell me.

#2

Your code is not visible.What is your logic?
Can you send your code again?

#3

#include <bits/stdc++.h>

using namespace std;

bool compare(string s1,string s2){

    int i=0;
    if(s1[i]==s2[i]){
       return s1.length()>s2.length();
    }
    return s1<s2;

}

int main()
{
int n;
cin>>n;
cin.get();
string s[1000];
for(int i=0;i<n;i++){
getline(cin,s[i]);
}
sort(s,s+n,compare);
for(int i=0;i<n;i++){
cout<<s[i]<<endl;
}

return 0;

}

#4

My doubt is not resolved yet,please tell me whats wrong in my code,oonly one test case is passed

#5

Your compare function was wrong.You have to compare character by character till first different character is found and if you couldn’t find a different character till min length of the two string then do length comparsion.
I have changed it in the code,Please see it.

#6

Please explain me how compare function work , how we decide it should return greater than aur less than ,if we compare two strings.

#7

Just read it on Google. I won’t be able to type all that and they have examples as well.

#8

Compare function is same as normal one, you have to write the logic for true and false condition.
See my code for more details
