Understanding the Make Number of Distinct Characters Equal Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given two 0-indexed strings word1 and word2. A move consists of choosing two indices i and j such that 0 <= i < word1.length and 0 <= j < word2.length and swapping word1[i] with word2[j]. Return true if it is possible to get the number of distinct characters in word1 and word2 to be equal with exactly one move. Return false otherwise.

Examples
word1 = "ac", word2 = "b"falseAny pair of swaps would yield two distinct characters in the first string, and one in the second string.
word1 = "abcc", word2 = "aab"trueWe swap index 2 of the first string with index 0 of the second string. The resulting strings are word1 = "abac" and word2 = "cab", which both have 3 distinct characters.
word1 = "abcde", word2 = "fghij"trueBoth resulting strings will have 5 distinct characters, regardless of which indices we swap.
Constraints
1 <= word1.length, word2.length <= 105word1 and word2 consist of only lowercase English letters.How Interview Coder Helps with Leetcode Problems
