The Weekly Challenge

HEADLINES

Welcome to the Week #301 of The Weekly Challenge.

Last week, I noticed a slight jump in contributions by Team PWC members. Well done team.

Ryan Thompson didn’t want to miss the celebration either. So here we have his contributions in Perl. Not only that we also received a blog post as bonus.

Talking about comeback, we have suprise contribution from Robert McIntosh in Python along with two blog posts, one for Task #1 and second for Task #2.

Thank you, Robert Ransbottom, for sharing solutions to Week #298.

Welcome back, Torgny Lyon, and thanks for sharing solutions to Perl.

Last but not least, thank you everyone for the best wishes and Christmas greetings. Have a fun and healthy Christmas with your loved one.

Task 1: Largest Number

Submitted by: Mohammad Sajid Anwar

You are given a list of positive integers, @ints.

Write a script to arrange all the elements in the given list such that they form the largest number and return it.

Example 1

Input: @ints = (20, 3)
Output: 320

Example 2

Input: @ints = (3, 30, 34, 5, 9)
Output: 9534330

Task 2: Hamming Distance

Submitted by: Mohammad Sajid Anwar

You are given an array of integers, @ints.

Write a script to return the sum of Hamming distances between all the pairs of the integers in the given array of integers.

The Hamming distance between two integers is the number of places in which their binary representations differ.

Example 1

Input: @ints = (4, 14, 2)
Output: 6

Binary representation:
4  => 0100
14 => 1110
2  => 0010

HammingDistance(4, 14) + HammingDistance(4, 2) + HammingDistance(14, 2) = 2 + 2 + 2 = 6.

Example 2

Input: @ints = (4, 14, 4)
Output: 4

Last date to submit the solution 23:59 (UK Time) Sunday 29^th December 2024.
