It was an online MCQ's + coding round consisting of 20 MCQ’s and 1 coding problem.

Q1. Check whether there exists a loop in the linked list.
Ans. 
Check for a loop in a linked list by using two pointers moving at different speeds.
• Use two pointers, one moving at double the speed of the other.

• If there is a loop, the two pointers will eventually meet at the same node.

• Example: 1 -> 2 -> 3 -> 4 -> 5 -> 2 (loop back to 2), the two pointers will meet at node 2.

The interview started at 8:30 pm in cc of Delhi Technological University itself and it was quite late. There was only a single interviewer and he asked me one coding question related to overflow of integers.

Q1. How can you check for integer overflow when multiplying two integers and ensure the result is stored correctly within an integer type?
Ans. 
To check for integer overflow when multiplying two integers, use the properties of integer overflow and check if the result is within the valid range of the integer type.
• Check if the signs of the two integers are the same to avoid overflow in case of multiplication.

• Use the properties of integer overflow to detect if the result exceeds the maximum or minimum value of the integer type.

• Consider using a larger data type or...read more

Q2. 
Reverse a Stack Using Recursion
You are given a stack of integers. Your task is to reverse the stack using recursion without using any extra space other than the internal stack space used due to recursion...read more
Ans. 
Reverse a stack using recursion without using any extra space other than the internal stack space.
• Use recursion to pop all elements from the original stack and store them in function call stack.

• Once the stack is empty, push the elements back in reverse order.

• Base case of recursion should be when the original stack is empty.

Q1. 
Convert a Binary Tree to its Mirror Tree
Given a binary tree, convert this binary tree into its mirror tree. A binary tree is a tree in which each parent node has at most two children. The mirror of a bin...read more
Ans. 
Convert a binary tree to its mirror tree by interchanging left and right children of all non-leaf nodes.
• Traverse the binary tree in a recursive manner.

• Swap the left and right children of each non-leaf node.

• Continue this process until all nodes have been processed.
