3 coding questions in 90 mins, 1st one is from arrays an easy question, 2nd one is related to stacks and queues relatively harder and last one is hard which i am also unable to attempt. I cracked the first two questions and my solutions passed all the test cases.

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.

Q1. Flatten a binary tree
Ans. 
Flatten a binary tree by converting it into a linked list in-place.
• Use a recursive approach to flatten the binary tree.

• Traverse the tree in a pre-order manner and keep track of the previous node.

• Set the left child of each node to null and the right child to the next node in the linked list.

• Example: Input: 1 -> 2 -> 5 -> 3 -> 4 -> null, Output: 1 -> null -> 2 -> null -> 3 -> null -> 4 -> null -> 5 -> null
