Which algorithm is used in the top tree data structure?

Correct Answer (Detailed Explanation is Below)

B. Divide and Conquer

Detailed Explanation

A Top Tree is a data structure used mainly for dynamic trees (like dynamic graph connectivity).

It works by:

• Dividing the tree into smaller clusters

• Processing those clusters

• Combining results

This follows the Divide and Conquer approach:

1. Divide the structure

2. Solve smaller parts

3. Merge results

❌ Why not others?

• Greedy → Used in algorithms like Prim’s, Kruskal’s

• Backtracking → Used in N-Queen, Sudoku

• Branch → Not a complete algorithm type (usually “Branch and Bound”)
