Hi Om,

There are no editorials visible for live contests. We are also not planning to have any editorials for the mock contest as they are more meant to get familiar with the platform. We can share the model solutions once the contest is over for reference.

so sir can you please help me with this problem?

contest will will be over after zco exam!
here is problem link :- https://codedrills.io/contests/zco-practice-contest-1/problems/string-changes

here is my attempt :-

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

int main(){
	int op,and;
	string s;
	string st="abcdefghijklmnopqrstuvwxyz";
	for(int i=0;i<100;i++){
	return 0;

@Om_Singh I would recommend running against the sample cases and seeing where it goes wrong. You can print out values in stderr (cert << op << end; for example and see the progress of how it is calculated.

As for you solution, it does not calculate what is asked, it compares against abcd... while the problem asks that adjacent characters not be the same. So think along those lines. Good luck!
