Q1. Implementation of Breadth First Search
Ans. 
Breadth First Search is a graph traversal algorithm that explores all the neighbor nodes at the present depth prior to moving on to the nodes at the next depth level.
• Start by visiting the root node and then visit all the neighbor nodes at the present depth level before moving on to the nodes at the next depth level.

• Use a queue data structure to keep track of the nodes to be visited.

• Mark each node as visited to avoid re...read more

Q2. Implementation of Depth First Search
Ans. 
Depth First Search is a graph traversal algorithm that explores as far as possible along each branch before backtracking.
• Start at a node and explore as far as possible along each branch before backtracking

• Use a stack to keep track of nodes to visit

• Mark visited nodes to avoid revisiting them

• Can be implemented recursively or iteratively

Q1. Swap Alternative nodes of a Linked list
Ans. 
Swap alternative nodes of a linked list
• Iterate through the linked list and swap the data of alternate nodes

• Use temporary variables to store data during swapping

• Ensure to handle cases where the linked list has an odd number of nodes

Q2. Reverse a Linked list
Ans. 
Reverse a linked list by changing the next pointers of each node
• Start with three pointers: current, prev, and next

• Iterate through the linked list, updating the next pointer of each node to point to the previous node

• Update prev, current, and next pointers for each iteration

• Example: 1 -> 2 -> 3 -> 4 -> null, after reversing: 4 -> 3 -> 2 -> 1 -> null
