LeetCodeArrayHash TableStringBit ManipulationCountingOpen on judge ↗

You are given a 0-indexed string array words. Two strings are similar if they consist of the same characters. - For example, "abca" and "cba" are similar since both consist of characters 'a', 'b', and 'c'. - However, "abacba" and "bcfd" are not similar since they do not consist of the same characters. Return the number of pairs (i, j) such that 0 <= i < j <= word.length - 1 and the two strings
