Q2. Hash map implementation
Ans. 
A hash map is a data structure that allows for efficient storage and retrieval of key-value pairs.
• Hash maps use a hash function to convert keys into array indices.

• Collisions can occur when multiple keys hash to the same index, requiring a collision resolution strategy.

• Common collision resolution strategies include chaining and open addressing.

• Hash maps have constant-time average case complexity for insertion, deletion,...read more

2 programming questions, MCQs based on OS, DBMS, OOPS and web fundamentals

Q1. Search In A 2D Matrix
You have been given a 2-D array 'MAT' of size M x N where 'M' and 'N' denote the number of rows and columns, respectively. The elements of each row are sorted ...read more
Ans. Brute Force
We have a brute force solution to this problem. We can simply traverse the matrix and check if ‘TARGET’ exists or not. 
Space Complexity: O(1)Explanation:
O(1)
 
Since, we are not using any extra space to find the number of pairs. Therefore, the overall space complexity will be O(1).
Time Complexity: O(m*n) - For 2d arraysExplanation:
O(M*N) where ‘M’ and ‘N’ denote the number of rows and columns in ‘M...read more

Q2. Reverse Linked List
You are given a Singly Linked List of integers. You need to reverse the Linked List by changing the links between nodes.
Input Format :
The first line of input contains a single integ...read more
Ans. Recursive Approach
One way is to use recursion to reverse the list. Divide the linked list in two halves, the first node and the rest of the list. Reverse the second half using recursion and append the first half, that is the first node at the end of the reversed linked list. Return the head of the reversed linked list.
 
Algorithm
 
• If the list contains only one node, return the head of the list.
• Else, divide the ...read more

This round had 2 coding questions and some basic questions revolving around OOPs

Q1. Palindromic Linked List
You are given a singly Linked List of integers. Your task is to return true if the given singly linked list is a palindrome otherwise returns false.
For example:
The given linked ...read more
Ans. Using Stack
1. The idea is to traverse the Linked List from head to tail and push every encountered node data into the stack.
2. Then we traverse the Linked List and for each node, we pop the top element from the stack and compare it with current node data of the Linked List. If they mismatch then the current linked list is not palindrome else if all elements match then the linked list is a palindrome.
Space Complexity: O(n)Exp...read more

Q2. Find the maximum level sum among all the levels in the Binary Tree
Given a Binary Tree with integer nodes, your task is to find the maximum level sum among all the levels in the Binary Tree. The sum of any...read more
Ans. Recursive Approach
Let’s traverse the given Binary tree using Recursion.The idea is to recursively store the sum of nodes of every level separately in a map.
 
• Take a map to store the sum of each level. 
• The recursive function has ‘ROOT’, current level, and map as its parameters.
  • Base Condition:  If ‘ROOT’ is NULL, return.
  • Add the value of the current node to the value mapped to the current level in the map.
  • Re...read more
