This was a 2 hour round consisting of 5 mcqs and 2 codes. The mcqs were pretty much simple based on DS, DBMS, OS, OOP, and C.

Q1. 
Rabbit Jumping Problem
Consider 'n' carrots numbered from 1 to 'n' and 'k' rabbits. Each rabbit jumps to carrots only at multiples of its respective jumping factor A_j (i.e., A_j, 2A_j, 3A_j, ...), for all ra...read more
Ans. 
Calculate uneaten carrots by rabbits with specific jumping factors.
• Iterate through each carrot and check if any rabbit jumps on it.

• Use the jumping factors to determine which carrots are eaten.

• Subtract the eaten carrots from the total to get the uneaten count.

Q2. 
Flip Bits Problem Explanation
Given an array of integers ARR of size N, consisting of 0s and 1s, you need to select a sub-array and flip its bits. Your task is to return the maximum count of 1s that can b...read more
Ans. 
Given an array of 0s and 1s, find the maximum count of 1s by flipping a sub-array at most once.
• Iterate through the array and keep track of the maximum count of 1s obtained by flipping a sub-array.

• Consider flipping a sub-array from index i to j by changing 0s to 1s and vice versa.

• Update the maximum count of 1s if the current count after flipping is greater.

• Return the maximum count of 1s obtained by flipping a sub-array

Follow Up:
Can you achie...read more
Ans. 
Find sum of maximum and minimum elements in an array with least number of comparisons.
• Iterate through the array and compare each element with current maximum and minimum to update them.

• Initialize max as smallest possible value and min as largest possible value.

• Return the sum of max and min after iterating through the array.

Questions based on programming, DBMS and puzzles were asked in this round.

Q1. 
Rearrange Array to Form Largest Number
Given an array ARR consisting of non-negative integers, rearrange the numbers to form the largest possible number. The digits within each number cannot be changed.
...read more
Ans. 
Rearrange the array elements to form the largest possible number by concatenating them.
• Sort the array elements in a custom way where the concatenation of two numbers results in a larger number.

• Use a custom comparator function while sorting the array elements.

• Convert the sorted array elements to a single string to get the largest possible number.

Q2. What is indexing in the context of databases?
Ans. 
Indexing in databases is a technique used to improve the speed of data retrieval by creating a data structure that allows for quick lookups.
• Indexes are created on columns in a database table to speed up the retrieval of rows that match a certain condition.

• They work similar to the index in a book, allowing the database to quickly find the relevant data without having to scan the entire table.

• Examples of indexes include ...read more

Q3. What are the advantages of B+ Trees in database management systems?
Ans. 
B+ Trees are advantageous in database management systems due to their ability to efficiently store and retrieve data.
• B+ Trees have a high fanout, allowing for more keys to be stored in each node, reducing the height of the tree and improving search performance.

• B+ Trees are balanced trees, ensuring that operations like search, insertion, and deletion have a predictable time complexity of O(log n).

• B+ Trees are optimized ...read more
