Questions & Step-by-Step Solutions
Which of the following is true about a complete binary tree?
Step 1: Understand what a binary tree is. A binary tree is a tree data structure where each node has at most two children, referred to as the left child and the right child.
Step 2: Learn about levels in a binary tree. The topmost node is at level 0, the nodes directly below it are at level 1, and so on.
Step 3: Know what a complete binary tree is. A complete binary tree is a type of binary tree where every level, except possibly the last one, is completely filled.
Step 4: Focus on the last level of a complete binary tree. The last level can be partially filled, but if it is, the nodes must be filled from the left side to the right side without any gaps.
