I appeared for an interview before Mar 2021.
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
