Show how the Boyer-Moore string matching algorithm works for the following input.How many comparisons of characters are done in each case?(a) T = AAAAAAAAAA, P = AAAB(b) T = ratsbatsandcats, P =cathat
Define "matching in algorithms" using your own words.
Is there an existing version of the Boyer-Moore string search algorithm in some form? Describe the steps that will be taken to put the plan into effect.

- Can you think of a good example of a Boyer-Moore string search algorithm implementation in the literature? Explain how to put the plan into action.arrow_forwardGiven an input string (s) and a pattern (p), implement wildcard pattern matching with support for '?' and '*' where: '?' Matches any single character. '*' Matches any sequence of characters (including the empty sequence). The matching should cover the entire input string (not partial). Example 1: Input: s = "aa", p = "a" Output: false Explanation: "a" does not match the entire string "aa". Example 2: Input: s = "aa", p = "*" Output: true Explanation: '*' matches any sequence. Example 3: Input: s = "cb", p = "?a" Output: false Explanation: '?' matches 'c', but the second letter is 'a', which does not match 'b'. Constraints: 0 <= s.length, p.length <= 2000 s contains only lowercase English letters. p contains only lowercase English letters, '?' or '*'.
