3435. Frequencies of Shortest Supersequences

LeetCodeArrayStringBit ManipulationGraph TheoryTopological SortEnumerationOpen on judge ↗

You are given an array of strings words. Find all shortest common supersequences (SCS) of words that are not permutations of each other. A shortest common supersequence is a string of minimum length that contains each string in words as a subsequence. Return a 2D array of integers freqs that represent all the SCSs. Each freqs[i] is an array of size 26, representing the frequency of each letter i
