Understanding Prim’s Algorithm for Minimum Spanning Tree in C++
Prim’s Algorithm is a popular greedy algorithm used to find the Minimum Spanning Tree (MST) of a connected, weighted graph.
Minimum Spanning Tree (MST) | Kruskal’s Algorithm in C++
Kruskal’s algorithm is one of the popular algorithms used to find an MST in a connected weighted graph. This algorithm is efficient, easy to understand, and guarantees the construction of a minimum-weight spanning tree.
Java Notes | Abstract class & Multi-level Inheritance
Each child class in the hierarchy is responsible for implementing abstract methods that have not been implemented by its superclasses.
Bellman-Ford Algorithm | Single source shortest path
This algorithm uses Relaxation, to find the shortest path between the source vertex and other vertices. It gradually expands the search space until the shortest path to the destination node is found.
Dijkstra’s Algorithm | Single source shortest path
Dijkstra’s algorithm works based on the principle of Greedy-approach, gradually expanding the search space until the shortest path to the destination node is found.
Nim’s Game | Code Implementation
Nim’s game is played with a set of heaps, each containing a certain number of objects or stones. Two players take turns removing objects from the heaps
Order Statistics | Selection Algorithm
“Order Statistics” is a concept discussed in the book “Introduction to Algorithms”. It pertains to finding the ith order statistics of a set of n elements in linear time. ith order statistics is the ith smallest element in a set of n elements.
Non-decreasing Subsequences Solution – LeetCode Solution [Medium]
Given an integer array nums, return all the different possible non-decreasing subsequences of the given array with at least two elements.
Is Subsequence – LeetCode Solution [Easy]
Given two strings s and t, return true if s is a subsequence of t, or false otherwise.
