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: Sorted Squares

Submitted by: Mohammad S Anwar

You are given a list of numbers.

Write a script to square each number in the list and return the sorted list, increasing order.

Example 1

Input: @list = (-2, -1, 0, 3, 4)
Output: (0, 1, 4, 9, 16)

Example 2

Input: @list = (5, -4, -1, 3, 6)
Output: (1, 9, 16, 25, 36)

Task 2: Travel Expenditure

Submitted by: Mohammad S Anwar

You are given two list, @costs and @days.

The list @costs contains the cost of three different types of travel cards you can buy.

For example @costs = (5, 30, 90)

Index 0 element represent the cost of  1 day  travel card.
Index 1 element represent the cost of  7 days travel card.
Index 2 element represent the cost of 30 days travel card.

The list @days contains the day number you want to travel in the year.

For example: @days = (1, 3, 4, 5, 6)

The above example means you want to travel on day 1, day 3, day 4, day 5 and day 6 of the year.

Write a script to find the minimum travel cost.

Example 1:

Input: @costs = (2, 7, 25)
       @days  = (1, 5, 6, 7, 9, 15)
Output: 11

On day 1, we buy a one day pass for 2 which would cover the day 1.
On day 5, we buy seven days pass for 7 which would cover days 5 - 9.
On day 15, we buy a one day pass for 2 which would cover the day 15.

So the total cost is 2 + 7 + 2 => 11.

Example 2:

Input: @costs = (2, 7, 25)
       @days  = (1, 2, 3, 5, 7, 10, 11, 12, 14, 20, 30, 31)
Output: 20

On day 1, we buy a seven days pass for 7 which would cover days 1 - 7.
On day 10, we buy a seven days pass for 7 which would cover days 10 - 14.
On day 20, we buy a one day pass for 2 which would cover day 20.
On day 30, we buy a one day pass for 2 which would cover day 30.
On day 31, we buy a one day pass for 2 which would cover day 31.

So the total cost is 7 + 7 + 2 + 2 + 2 => 20.


Last date to submit the solution 23:59 (UK Time) Sunday 4th June 2023.
