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 2023. 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 2023. 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: Fun Sort

Submitted by: Mohammad S Anwar

You are given a list of positive integers.

Write a script to sort the all even integers first then all odds in ascending order.

Example 1

Input: @list = (1,2,3,4,5,6)
Output: (2,4,6,1,3,5)

Example 2

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

Example 3

Input: @list = (1)
Output: (1)

Task 2: Shortest Route

Submitted by: Mohammad S Anwar

You are given a list of bidirectional routes defining a network of nodes, as well as source and destination node numbers.

Write a script to find the route from source to destination that passes through fewest nodes.

Example 1:

Input: @routes = ([1,2,6], [5,6,7])
       $source = 1
       $destination = 7

Output: (1,2,6,7)

Source (1) is part of route [1,2,6] so the journey looks like 1 -> 2 -> 6
then jump to route [5,6,7] and takes the route 6 -> 7.
So the final route is (1,2,6,7)

Example 2:

Input: @routes = ([1,2,3], [4,5,6])
       $source = 2
       $destination = 5

Output: -1

Example 3:

Input: @routes = ([1,2,3], [4,5,6], [3,8,9], [7,8])
       $source = 1
       $destination = 7
Output: (1,2,3,8,7)

Source (1) is part of route [1,2,3] so the journey looks like 1 -> 2 -> 3
then jump to route [3,8,9] and takes the route 3 -> 8
then jump to route [7,8] and takes the route 8 -> 7
So the final route is (1,2,3,8,7)

Last date to submit the solution 23:59 (UK Time) Sunday 23rd April 2023.
