getline(cin,s);
    
char ch='a';

for(int i=0; i<k; i++)
{   
    for(int j=0; j<s.length(); j++)
    {
        if(s[j]!=ch)
        {

Hello @sharmaharsh9944,

In your code you are only looking for the strings of ‘a’.
You have to also check for ‘b’.
Example:
4
baabb
Expexted Output:
5 (for bbbbb)
//Replaced two ‘a’ with ‘b’
Your Output:
4 (for aaaab)

Hope, this would help.
Give a like if you are satisfied.
