The 0-1 knapsack problem asks: given a set of items each with a weight and a value, and a knapsack with a maximum weight capacity, which items should you pack to maximize the total value? Each item can be taken once (0-1) — you cannot take a fraction. This is a classic dynamic programming problem …
Heap Sort is a comparison-based sorting algorithm that uses a binary heap data structure. Its standout property: it is guaranteed O(n log n) in all cases — best, average, and worst — while using only O(1) extra memory. No Quick Sort worst-case surprises, no Merge Sort extra array. Key Concept — The Max-Heap A max-heap …
Quick Sort is one of the fastest and most widely used sorting algorithms. It uses a divide-and-conquer strategy: pick a pivot element, partition the array so everything smaller than the pivot is on its left and everything larger is on its right, then recursively sort each side. The pivot ends up in its final sorted …
A priority queue is a data structure where each element is served according to its priority rather than just the order it arrived. A multiple priority queue implements this with several separate queues — one per priority level — so that higher-priority items are always removed before lower-priority ones. This C program builds a simple …
C Recursion: C Program to implement Towers of Hanoi and Binary Search using the Recursion method. Recursive functions solves the complexity of the problem by calling the function again and again itself. Using recursive methods we can save execution time and memory. In this program we have two recursive functions for Binary search and the …
A binary search tree (BST) in C is a binary tree where every node satisfies one invariant: all values in the left subtree are less than the node, and all values in the right subtree are greater. This ordering means search, insert, and delete all run in O(h) time — where h is the tree …
