Due to that my interest in coding and development increased and I decided to pursue computer science for my graduation. After joining the college I started taking part in hackathons and various coding competitions hosted by Hackerrank, Hackerearth, etc.

Coding problem3

For me assessment was at 4.30 in the evening. The round was about 120 minutes long. It had 3 coding questions easy, medium, and high level. And, it contained some aptitude questions on profit and loss, SI, CI, etc, which will be easy to solve. It also contained logical questions like seating arrangement directions. And vocabulary round was also there. To solve a coding round you need to have a basic understanding. For me the easy question was to find out the prime number in the array, and the medium level question was on profit maximization and another one was the jumping cloud problem. There will be 6 coding questions which we need to solve 3.(one from easy, medium and hard). I solved two coding questions. And the aptitude part was easy, most like other companies. you can solve that very easily.

You are given a positive integer ‘N’. Your task is to print all prime numbers less than or equal to N.

Note: A prime number is a natural number that is divisible only by 1 and itself. Example - 2, 3, 17, etc.

You can assume that the value of N will always be greater than 1. So, the answer will always exist.

You are given a positive integer N, your task is to find all the Jumping Numbers smaller than or equal to N.

A number is defined as a Jumping Number if all adjacent digits in it have an absolute difference of 1.

Example :
2, 23, and 4343456 are Jumping numbers but 296 and 89498 are not.
Note:
The difference between ‘9’ and ‘0’ is not considered as 1. All single-digit numbers are considered as Jumping Numbers.
