Arrange given numbers to form the biggest number

Form Biggest Number

Hello @rprahulpal03 the simple logic you can apply in this is that take the sort function and take compare in it .
in that compare function return the max of
a+b or b+a .
in this way you can do this question.
Here for your reference i am attaching the code:

#include

using namespace std;

bool compare(string a,string b){

return a+b>b+a;

}

int main()

{

int t;

cin>>t;

for (; t > 0; t--)

{

    int n;

    cin>>n;

    cin.get();

    string a[n];

    for(int i=0;i<n;i++){

        cin>>a[i];

    }

    sort(a,&a[n],compare);

    for(int i=0;i<n;i++){

        cout<<a[i];

    }

}

}

#include<bits/stdc++.h>
using namespace std;

bool compare(string a,string b){

return a+b>b+a;

}

int main()

{

int t;

cin>>t;

for (; t > 0; t–)

{

int n;

cin>>n;

cin.get();

string a[n];

for(int i=0;i<n;i++){

    cin>>a[i];

}

sort(a,&a[n],compare);

for(int i=0;i<n;i++){

    cout<<a[i];

}

cout<<endl;
}
}

corrected code:
you have to print for every output in new line.
