Why is a Bipartite graph with an odd number of vertices a Non-Hamiltonian graph?
A Hamiltonian cycle, also known as a Hamilton cycle or Hamiltonian circuit, is a cycle in a graph that visits every vertex exactly once, except for the starting vertex.
Knuth-Morris-Pratt (KMP) | String Searching Algorithm
The KMP algorithm improves the efficiency of string searching by utilizing the information gathered from previous character comparisons. It avoids unnecessary character comparisons by exploiting the knowledge of the pattern itself.
Permutations of a string
Each of these permutations represents a unique arrangement of the elements. Total number of permutations of a set will always be n!
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.
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.
