Kruskal algorithm is one of the two commonly used algorithms for finding a Minimum Spanning Tree. Here the C code for implementing this algorithm has been presented. The code operates on the Input File which can be downloaded and must be in the same directory in which the program is to be executed. This code [...]

C code for permutation
Posted by Saurabh on February 16th, 2010
Finding all the permutations for any given set of items has always been an area of interest for programmers. A very simple algorithm for finding all the permutations, the Bell Algorithm has already been presented.
Here the C code implementing Bell algorithm, for finding all the possible permutations has been given. The program assumes that [...]
Tracing path to a Website
Posted by Saurabh on February 16th, 2010
Very often some website becomes unreachable and we couldn’t understand the reason of that. In such a case we must know the path of a data packet from our computer to the website so that we can see where the connection has failed. In windows the command for tracing path to a website is ‘tracert’ [...]
