Kruskal’s algorithm finds the minimum spanning tree (MST) of a weighted, connected, undirected graph — the cheapest possible set of edges that connects every vertex with no cycles. It’s the classic greedy approach: sort all edges by weight, then keep taking the cheapest edge that doesn’t form a cycle. Road networks, electrical wiring, and network …
Data structures using C, Here we solve the Warshall’s algorithm using C Programming Language. Warshall’s algorithm enables to compute the transitive closure of the adjacency matrix of any digraph. /************************************************************ You can use all the programs on www.c-program-example.com* for personal and learning purposes.

Floyd-Warshall algorithm finds the shortest paths between every pair of vertices in a weighted graph in a single O(V³) pass. While Dijkstra’s algorithm starts from one source vertex, Floyd-Warshall answers the all-pairs problem: “what is the shortest path from vertex i to vertex j for every i and j?” It uses dynamic programming — systematically …
The N-Queens problem asks: place N chess queens on an N×N board so that no two queens share a row, column, or diagonal. The standard C solution uses backtracking — place queens one row at a time, try every column in that row, recurse if the placement is safe, and undo (backtrack) if a dead …
Prim’s algorithm finds the Minimum Spanning Tree (MST) of a weighted undirected graph — the set of edges that connects all vertices at the lowest possible total cost. It works by growing a single tree: start at any vertex, then repeatedly add the cheapest edge that reaches a vertex not yet in the tree, until …
C Program to find the substring in a String using the Horspool method. This algorithm uses the Brute-Forse method which searches the text between 0 and n-m, and after each cycle it shifts the pattern by one position to the right.
