Working of Second loop

#1

while (i < j)

{
    while (j < s.size() - 1 && s[j + 1] == ch){
        j++;
    }

    int currentLength = j - i + 1;

    ans = max(ans, currentLength);

    i++;

    if (j < s.size() - 1 && s[i - 1] != ch)
        j++;
}
return ans;

}

can you please explain what’s the second loop doing .
and you please refer a video for it

@sinhadivyam19
second while loop is for just moving the index j.
for eg if ch==‘a’ then do j++ until next index i.e. j+1 is equal to ch.
so it will cover all the consecutive index having character as ch.

If you have any further doubt in this, then please write the code and share its ide link.
If it is clear now, then please mark this doubt as resolved.
