- Q1. Difference between sorting algorithms
- Ans.
Sorting algorithms are methods used to arrange elements in a specific order.
Different sorting algorithms include bubble sort, selection sort, insertion sort, merge sort, quick sort, and heap sort.
Some algorithms are more efficient than others depending on the size of the data set and the initial order of the elements.
For example, quick sort is generally faster than bubble sort for large data sets.
- Q2. BFS and DFS in trees and imlementing them
- Ans.
BFS and DFS are traversal algorithms used in trees. BFS explores level by level, while DFS explores depth first.
BFS (Breadth-First Search) visits nodes level by level, using a queue. Example: traversing a binary tree level by level.
DFS (Depth-First Search) explores as far as possible along each branch before backtracking. Example: in-order traversal of a binary tree.
