In a min-heap, which of the following is true about the parent and child nodes?

Step 1: Understand what a min-heap is. A min-heap is a special type of binary tree where the smallest value is at the top (the root).
Step 2: In a min-heap, each parent node must be less than or equal to its child nodes. This means that if you look at any parent, its value will always be smaller than or equal to the values of its children.
Step 3: This property ensures that the smallest element in the entire heap is always at the root of the tree.
Step 4: Therefore, if you want to find the minimum element in a min-heap, you can simply look at the root node.

Min-Heap Properties – In a min-heap, each parent node is less than or equal to its child nodes, which maintains the heap property.
