Data structures in typescript 17 binomial heap introduction

okay, let's dive deep into binomial heaps, specifically within the context of typescript, providing a comprehensive tutorial with explanations and a code example.

**binomial heaps: a detailed guide**

**1. what are binomial heaps?**

a binomial heap is a type of heap data structure that is a collection of binomial trees. it's particularly valuable because it supports efficient merging (union) of two heaps. this merge operation is a cornerstone of many algorithmic applications.

* **key features:**

* **collection of binomial trees:** a binomial heap is not a single tree but a set of binomial trees. each tree satisfies the *min-heap* (or *max-heap*, depending on the application) property, where the value of each node is less than or equal to (or greater than or equal to) the values of its children.
* **unique degree property:** a binomial heap can contain at most one binomial tree of each degree (order). the degree of a binomial tree is defined as the number of children of its root node. this uniqueness is crucial for efficient operations.
* **efficient merge:** the `merge` operation has a time complexity of o(log n), where n is the total number of nodes in the two heaps being merged. this is what distinguishes it from other heap structures like binary heaps, which can have o(n) merge complexity.
* **lazy operations:** binomial heaps tend to favour a "lazy" approach. for example, when decreasing a key, the change may not immediately propagate throughout the entire structure, delaying some restructuring until a later operation like `extractmin`.

**2. binomial trees**

before we can understand a binomial heap, we need to understand binomial trees.

* **definition:**

* a binomial tree of order 0 (b0) consists of a single node.
* a binomial tree of order k (bk) is formed by taking two binomial trees of order k-1 (bk-1) and making the root of one the leftmost child of the root of the other.

* **properties:**

* a bi ...
