The beauty of programming: deleting a node from a single-chain table without headers. 1. Problem Description Suppose there is a single-chain table without a header pointer. A pointer points to a node (not the first or the last) in the middle of the

Graph Algorithm (7) --- use the query set to find the Minimum Spanning Tree The most typical algorithm is the prim algorithm and the kruskal algorithm. In terms of time efficiency, kruskal is superior. For the implementation of kruskal, here we use
