Contest Preparation Algorithm This solution handles two special cases before applying the general formulla: #include <iostream> using namespace std; int main() { int n, m; cin >> n >> m; if (n == 0) { cout << 0 << endl; } else if (n <= m) { cout << 2 << e...
Sorting Squared Elements of a Monotonic Array Given an integer sequence arranged in non-decreasing order, the objective is to generate a new array containing the squares of each element, also sorted in non-decreasing order. Because the original input may contain negative values, squaring them can in...
Sliding Window Algorithm Paterns Core Implementation Template const slidingWindowSolution = (inputString) => { // Initialize tracking variables let [primaryVar, secondaryVar] = [initialValue1, initialValue2]; // Set window boundaries let windowStart = 0; const results = []; for (let windowEnd = 0...
Given a string s, determine the length of the longest substring that contains no repeating characters. Example 1: Input: s = "abcabcbb" Output: 3 Explanation: The answer is "abc", with the length of 3. Example 2: Input: s = "bbbbb" Output: 1 Explanation: The answer is &...
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...
