What is a Suffix Tree/Array? What string problems does it solve?
Difficulty: 5/10
Suffix Trees and Suffix Arrays
A suffix tree is a compressed trie containing all suffixes of a string, while a suffix array stores the starting positions of all suffixes in lexicographically sorted order. They support advanced string-processing tasks such as substring search, longest repeated substring, longest common substring, and pattern matching.
