Problem : To generate all r-Permutation with repetitions of a set of distinct elements
Before we start discussing about the implementation we will go through the basic definitions of Permutations. Then we discuss the method to generate r-Permutations with repetitions with examples, and at last we implement a C Language Program of the problem. Continue reading.
Problem:Developing Algorithm to interchange of the values stored in two given variables.
The exchanging of the values between two given variables is commonly known as value “swap” and the process is known as “swapping”.This can be archived by various approaches. Below, we will discuss about two different approaches with a total of three processes, and see their benefits and pitfalls.
Jumbled Word: A string of characters is given, the task is to find all the meaningful words that can be created by rearranging its letters. Solving a jumble word means to find all the meaningful words that can be made with the initial string.
In this article first we will describe how a jumbled word can be solved and then we present a very simple computer program. After this we present an advanced computer program which will make the solution very fast with the help of a specially designed tree.
Here is another related post Jumbled word solver with C++ and Perl implementation with hash and list: Jumble word solver again.
*Please Note:* This article is very old and lengthy, I am planning for either a revision or a rewrite for the trie tree part which reflect the recent modifications. At the time I wrote this I did not know that the datastructure which I worked out was a trie :) therefore the long explanation.

Twin Prime: A twin prime is a set of two prime numbers whose absolute difference is 2. Let p1 and p2 primes such that p2 – p1 = 2, then the set { p1 , p2 } are twin primes.
The objective of this article is to describe the basic algorithm to search for the twin primes first, and then make some modifications to make it better and faster. At last we present the final code
