For example construction of a binomial heap with 13 nodes-
1. First write its binary representation,like for 13, its 1101.
2. So,we'll have trees 0,2,3 that is B0,B2,B3 with B0->1, B2->4 AND B3-> 8 nodes.

A binomial heap H with n = 13 nodes.
(a) The heap consists of binomial trees B0, B2, and B3, which have 1, 4, and 8 nodes respectively, totaling n = 13 nodes. Since each binomial tree is min-heap-ordered, the key of any node is no less than the key of its parent. Also shown is the root list, which is a linked list of roots in order of increasing degree.
(b) A more detailed representation of binomial heap H . Each binomial tree is stored in the left child, right-sibling representation, and each node stores its degree.
This heap consists of at most [lg n]+1 binomial trees i.e. 3+1=4.
