Longest String Chain Problem Statement You are given an array of strings, words. A string chain is a sequence of words w1, w2, ..., wk such that for every i from 1 to k 1, wi+1 is formed by inserting exactly one character anywhere in wi. You need to return the length of the longest possible string chain that can be formed from the given words array. Example Input: Output: Explanation: One possible longest string chain is "a" "ba" "bda" "bdca". Its length is 4. Constraints (No specific constraints provided in the original content.)
