Huffman Coding Compression Algorithm

Huffman Coding (also known as Huffman Encoding) is a algorithm for┬ádoing data compression and it forms the basic idea behind file compression. This post talks about fixed length and variable length encoding, uniquely decodable codes, prefix rules and construction of Huffman Tree.  

Treap Data Structure

A Treap Data Structure is basically a combination of a binary search tree and a heap.   Binary Search Trees – Deletions and additions of nodes can make the tree unbalanced (heavier on sides, therefore, the property we value about BSTs, the ability to distribute data by equal divisions, goes out of whack). Therefore we …

External Merge Sort Algorithm

We can efficiently sort massive amounts of data using External Merge Sort Algorithm, when the data being sorted don’t fit into the main memory (which is usually RAM) and resides in the slower external memory (which is usually a hard disk).
