Question

The nn nodes in a binary tree can be visited in:

a. Θ(1) time
b. Θ(log n)
c. Θ(n) time
d. Θ(nlogn) time
e. Θ(n²) time

Answer 1

The time complexity for visiting all nn nodes in a binary tree is Θ(n).

Step-by-step explanation:

The time complexity for visiting all nn nodes in a binary tree depends on the number of nodes and the structure of the tree. In the worst case scenario, we need to visit each node once, resulting in a time complexity of Θ(n). This means that the time required to visit all nodes grows linearly with the number of nodes in the tree.
