Give me a code to lexicographically largest string possible consisting of at most K consecutive similar characters and the other steps required given the following:
Lexicographically largest string possible consisting of at most K consecutive similar characters | Function to return nearest lower character.
Traverse charset from start - 1.
If no character can be appended.
Function to find largest string.
Stores the frequency of characters.
Traverse the string.
Append larger character.
Decrease count in charset.
Increase count.
Check if count reached to charLimit.
Find nearest lower char.
If no character can be appended.
Append nearest lower character.
Reset count for next calculation.
Return new largest string.
