The Weekly Challenge

09. TASK #1: Read N-characters

10. TASK #2: Search Insert Position

HEADLINES

We are fast approaching the 100th week of the weekly challenge.

Have you got any plan?

Any suggestion to make it a special?

Do you know any fun and challenging tasks that we have not done yet for the special week?

Last week, I asked for suggestion of Award names. So far, I have received two names Witty Code Award and Warden of Code Award.

Please do share your ideas as we still have 2 weeks before the big event.

Did you notice, today is the first Monday of the month and time to announce the Champion?

Believe it or not, picking one name among so many is the most difficult task for me.

We are proud to declare Stuart Little as the first Champion of the year 2021.

I request all Perl and Raku reviewers, current and past, please send your three nominations each for year 2019 and 2020.

You should receive the formal email request soon in this regard.

I formally request all Team PWC members to nominate their favourite blogger for year 2019 and 2020.

Let’s welcome three new members to Team PWC i.e. Jan Hoogenraad, Robbie Hatley and Kai Burgdorf.

Last but not least, I would like to thank Dave Cross for patching the content for website. Much appreciated.

This week, we received 58 contributions from guests in 21 languages.

I would like to THANK each and every guest contributors.

Languages Summary

Last but not least, I would like to thank each and every member for their support and encouragement.

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 2021. 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 2021. The amount doesn’t have to be huge. However, it would be nice to show off bunch of supporters. If a big organisation came forward and supported us then that would be the ultimate achievement.

TASK #1 › Read N-characters

Submitted by: Mohammad S Anwar

You are given file $FILE.

Create subroutine readN($FILE, $number) returns the first n-characters and moves the pointer to the (n+1)th character.

Example:

Input: Suppose the file (input.txt) contains "1234567890"
Output:
    print readN("input.txt", 4); # returns "1234"
    print readN("input.txt", 4); # returns "5678"
    print readN("input.txt", 4); # returns "90"

TASK #2 › Search Insert Position

Submitted by: Mohammad S Anwar

You are given a sorted array of distinct integers @N and a target $N.

Write a script to return the index of the given target if found otherwise place the target in the sorted array and return the index.

Example 1:

Input: @N = (1, 2, 3, 4) and $N = 3
Output: 2 since the target 3 is in the array at the index 2.

Example 2:

Input: @N = (1, 3, 5, 7) and $N = 6
Output: 3 since the target 6 is missing and should be placed at the index 3.

Example 3:

Input: @N = (12, 14, 16, 18) and $N = 10
Output: 0 since the target 10 is missing and should be placed at the index 0.

Example 4:

Input: @N = (11, 13, 15, 17) and $N = 19
Output: 4 since the target 19 is missing and should be placed at the index 4.

Last date to submit the solution 23:59 (UK Time) Sunday 7th February 2021.
