removeTrailingChars

removeTrailingChars is a function commonly found in programming libraries and string manipulation utilities. Its primary purpose is to trim a specified set of characters from the end of a given string. When a string is processed by removeTrailingChars, it iterates from the rightmost character and checks if it belongs to the set of characters designated for removal. If it does, the character is removed. This process continues until a character is encountered that is not in the removal set, or until the string becomes empty.

The function typically takes two arguments: the string to be modified and a string or set containing the characters to be removed. For example, if you have the string "example!!!" and you want to remove trailing exclamation marks, you would call removeTrailingChars("example!!!", "!") which would return "example". Similarly, removing trailing spaces from a string like " hello world " by calling removeTrailingChars(" hello world ", " ") would result in " hello world".

This utility is particularly useful in data cleaning and parsing scenarios where strings might have extraneous characters at their end due to input errors, data formatting inconsistencies, or specific protocol requirements. It helps in standardizing string data, making it easier to compare, process, and display. The behavior of removeTrailingChars is deterministic; it will always remove all occurrences of the specified trailing characters.
