The edit distance problem requires transforming one string into another using the minimum number of specific operations. The allowed modifications include deleting a character, inserting a new character, or substituting an existing character. The goal is to compute the lowest cost sequence of operat...
Manacher's Algorithm Implementation for finding the longest palindromic substring: #include <iostream> #include <vector> #include <algorithm> using namespace std; vector<int> manacher(const string &s) { string t = "#"; for(char c : s) t += c, t += '#'; int n = t...
Sliding window algorithms efficiently solve substring and subarray problems with linear time complexity. This technique uses two pointers to define a window that expands and contracts based on conditions. A basic sliding window structure in C: #include <stdio.h> #include <string.h> void...
