WebA string-matching algorithm wants to find the starting index m in string S[] that matches the search word W[]. The most straightforward algorithm, known as the " Brute-force " or "Naive" algorithm, is to look for a word match at each index m , i.e. the position in the string being searched that corresponds to the character S[m] .

WebFeb 28, 2024 · 1 Answer. Sorted by: 2. The running time indeed belongs to O (m (n-m)). But as the Big-O notation is an upper bound, this is also O (mn), as mn ≥ m (n-m). In practice, no harm is done by this simplification, as you usually expect the length of the search string to be proportional to that of the pattern. Then m = αn yields m (n-m) = mn (1-α).
