As we all knew, Week 203 broke the continuity of reaching the magical figure of 100+ contributions. With handful of late submissions, we managed to reduced the gap. As of today, we have received 91 contributions for the Week 203. But the Week 204 brought us back on track with 100+ contributions once again. Thank you Team PWC for your support and contributions..

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: Third Highest

Submitted by: Mohammad S Anwar

You are given an array of integers.

Write a script to find out the Third Highest if found otherwise return the maximum.

Example 1

Input: @array = (5,3,4)
Output: 3

First highest is 5. Second highest is 4. Third highest is 3.

Example 2

Input: @array = (5,6)
Output: 6

First highest is 6. Second highest is 5. Third highest is missing, so maximum is returned.

Example 3

Input: @array = (5,4,4,3)
Output: 3

First highest is 5. Second highest is 4. Third highest is 3.

Task 2: Maximum XOR

Submitted by: Mohammad S Anwar

You are given an array of integers.

Write a script to find the highest value obtained by XORing any two distinct members of the array.

Example 1

Input: @array = (1,2,3,4,5,6,7)
Output: 7

The maximum result of 1 xor 6 = 7.

Example 2

Input: @array = (2,4,1,3)
Output: 7

The maximum result of 4 xor 3 = 7.

Example 3

Input: @array = (10,5,7,12,8)
Output: 15

The maximum result of 10 xor 5 = 15.


Last date to submit the solution 23:59 (UK Time) Sunday 26th February 2023.
