WebDec 1, 2024 · Suffixes of the string are “”, “C”, “BC”, and “ABC”. We search for lps in sub-patterns. More clearly we focus on sub-strings of patterns that are both prefix and suffix. For each sub-pattern pat [0..i] where i = 0 to m-1, lps [i] stores the length of the maximum matching proper prefix which is also a suffix of the sub-pattern pat [0..i].
