SQL joins are used to combine data from two or more tables based on a related column between them.
Inner join: returns only the matching rows from both tables
Left join: returns all the rows from the left table and matching rows from the right table
Right join: returns all the rows from the right table and matching rows from the left table
Full outer join: returns all the rows from both tables, with NULL values in the colu...

OOPs is a programming paradigm based on the concept of objects that interact with each other.
OOPs stands for Object-Oriented Programming.
It focuses on creating objects that have properties and methods.
Encapsulation, Inheritance, and Polymorphism are the three main pillars of OOPs.
Encapsulation is the process of hiding the implementation details of an object.
Inheritance allows a new class to be based on an existing clas...

Binary search algorithm should be used to minimize time complexity.
Binary search algorithm has a time complexity of O(log n).
It is efficient for searching in a sorted array.
The algorithm works by repeatedly dividing the search interval in half.
Example: If the array is [1, 3, 5, 7, 9] and we want to insert 6, we can use binary search to find the index where 6 should be inserted.
Once we find the index, we can shift the e...

Round duration - 60 minutes
Round difficulty - Easy
This was an easy round which went really smooth.
Calculate the Nth term in the Fibonacci sequence, where the sequence is defined as follows: F(n) = F(n-1) + F(n-2)
, with initial conditions F(1) = F(2) = 1
.
Calculate the Nth Fibonacci number efficiently using dynamic programming.
Use dynamic programming to store previously calculated Fibonacci numbers to avoid redundant calculations.
Start with base cases F(1) and F(2) as 1, then iteratively calculate F(n) using F(n-1) and F(n-2).
Ensure the input N is within the constraints 1 <= N <= 10000.
Example: For N = 5, the 5th Fibonacci number is 5 (1, 1, 2, 3, 5).
Given a positive integer N
, your task is to determine and return all prime numbers less than or equal to N
.
N = 10
2 3 5 7
N = 20
Implement a function to return all prime numbers less than or equal to a given positive integer N.
Create a function that takes a positive integer N as input
Iterate from 2 to N and check if each number is prime
Use a helper function to determine if a number is prime
Return an array of all prime numbers less than or equal to N
A merge join in SQL is a method of combining two sorted datasets by matching corresponding rows based on a specified condition.
Merge join is used when joining two large datasets that are already sorted.
It is more efficient than other join methods like nested loop join or hash join for sorted datasets.
The join condition must be an equality condition.
Example: SELECT * FROM table1 INNER JOIN table2 ON table1.id = table2.i
