A binomial Tree B0 is consists of a single node. A binomial tree Bk is consisting of two binomial tree Bk-1. That are linked together. The root of one is the left most child of the root of the other. Some binomial heaps are like below −.

It is important as an implementation of the mergeable heap abstract data type (also called meldable heap), which is a priority queue supporting merge operation. It is implemented as a heap similar to a binary heap but using a special tree structure that is different from the complete binary trees used by binary heaps. Binomial heaps were invented in 1978 by J…
