cout<<out;
return 0;
}
how should i modify this code its giving test case error
@Somith you can see for eg:- “aaa” your code will fail.
So rather than assigning something to string ‘out’ , you can just modifying the original array and atlast return the index of the modified array till which it contains elements.
Also one thing to note here is string in C++ STL are null terminated so that can also be reason for some wrong output.
