WebLet LCP ( s, t) be the length of the longest common prefix of strings s and t. Also let s [ x … y] be the substring of s from index x to index y (inclusive). For example, if s = " abcde ", then s [ 1 … 3] = " abc ", s [ 2 … 5] = " bcde ". You are given a string s of length n and q queries. WebMay 4, 2024 · A prefix is a letter or a group of letters attached to the beginning of a word (or word root) that partly indicates its meaning.
