Our solo sponsor Pete Sergeant has been a great support to keep us motivated. We are lucky that he agreed to continue the journey with us in the year 2022. I would like to personally thank Pete and his entire team for their generosity. It would be great if we could add few more to sponsor the prize money so that we could go back and declare weekly champions as we have done in the past. I hope and wish this will become possible in 2022. The amount doesn’t have to be huge. However, it would be nice to show off bunch of supporters. If an organisation comes forward and supports us then that would be the ultimate achievement.

Task 1: Max Gap

Submitted by: Mohammad S Anwar

You are given a list of integers, @list.

Write a script to find the total pairs in the sorted list where 2 consecutive elements has the max gap. If the list contains less then 2 elements then return 0.


Example 1

Input:  @list = (2,5,8,1)
Output: 2

Since the sorted list (1,2,5,8) has 2 such pairs (2,5) and (5,8)

Example 2

Input: @list = (3)
Output: 0

Task 2: Prime Count

Submitted by: Mohammad S Anwar

You are given an integer $n > 0.

Write a script to print the count of primes less than $n.

Example 1

Input: $n = 10
Output: 4 as in there are 4 primes less than 10 are 2, 3, 5 ,7.

Example 2

Input: $n = 15
Output: 6

Example 3

Input: $n = 1
Output: 0

Example 4
