1. Min-Heap Implementation in TypeScript

We first define a generic MinHeap class with the following operations:

• size(): Returns the number of elements in the heap.
• peek(): Returns the minimum (root) without removing it.
• push(value): Inserts a value, keeping the heap structure.
• pop(): Removes and returns the minimum (root).
• heapifyUp() and heapifyDown(): Internal methods to maintain heap order.
