WebMay 9, 2024 · Probably all you need to implement is constructors and MyReversedString& operator [] (size_t i), which simply returns s [len - i - 1]. BTW, pass your string by (const) reference instead of by value as you are currently -- the copying is wasteful, especially for long strings. Using s [len - i - 1] works, until you start searching backwards from ... WebMay 9, 2024 · Horspool is a simplified version of Boyer-Moore (with only a bad character rule) and uses smaller internal tables. The average complexity is linear, but the worst-case …

WebThere are many algorithms that start from the end. The simplest are the Horspool-type algorithms. The Horspool algorithm checks rst the text character aligned with the last pattern character. If it doesn't match, move (shift) the pattern forward until there is a match. Example 2.10: Horspool ainaise sti-aina inen ainaine/n ainaine//n ainainen 81
