Understanding the Remove Letter To Equalize Frequency Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given a 0-indexed string word, consisting of lowercase English letters. You need to select one index and remove the letter at that index from word so that the frequency of every letter present in word is equal. Return true if it is possible to remove one letter so that the frequency of all letters in word are equal, and false otherwise. Note: The frequency of a letter x is the number of times it occurs in the string. You must remove exactly one letter and cannot choose to do nothing.
