10. TASK #2: Multiplication Table

HEADLINES

Last week, I spoke about celebrating 1000 days of The Weekly Challenge by giving away FREE T-shirt to all the champions of the weekly challenge.

I am overwhelmed by the support to the campaign. I have created blog post with all the details. Please check it out and share your suggestions as well.

We received the first contribution in Perlby newly joined member, Jake.

Simon Green shared solutions in Python for the first time.

I have also participated this week and shared solutions in Perl, Raku, Java, Python and Swift.

I am not sure if you noticed it. We have been receiving guest contributions regularly. For the last 7 weeks, we have received 50+ contributions every week.

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 an organisation comes forward and supports us then that would be the ultimate achievement.

TASK #1 › Add Binary

Submitted by: Mohammad S Anwar

You are given two decimal-coded binary numbers, $a and $b.

Write a script to simulate the addition of the given binary numbers.

The script should simulate something like $a + $b. (operator overloading)

Example 1

Input: $a = 11; $b = 1;
Output: 100

Example 2

Input: $a = 101; $b = 1;
Output: 110

Example 3

Input: $a = 100; $b = 11;
Output: 111

TASK #2 › Multiplication Table

Submitted by: Mohammad S Anwar

You are given 3 positive integers, $i, $j and $k.

Write a script to print the $kth element in the sorted multiplication table of $i and $j.

Example 1

Input: $i = 2; $j = 3; $k = 4
Output: 3

Since the multiplication of 2 x 3 is as below:

    1 2 3
    2 4 6

The sorted multiplication table:

    1 2 2 3 4 6

Now the 4th element in the table is "3".

Example 2

Input: $i = 3; $j = 3; $k = 6
Output: 4

Since the multiplication of 3 x 3 is as below:

    1 2 3
    2 4 6
    3 6 9

The sorted multiplication table:

    1 2 2 3 3 4 6 6 9

Now the 6th element in the table is "4".

Last date to submit the solution 23:59 (UK Time) Sunday 28th November 2021.
