The Weekly Challenge

HEADLINES

Welcome to the Week #284 of The Weekly Challenge.

Last week we had another member, Peter Meszaros joining Paulo Custodio dealing with past week challenges. It gives me immense pleasure to see the flood of regular contributions. Thank you for your continuous support and contributions.

Thank you, Reinier Maliepaard, for sharing the special ChatGPT version of the Task #1.

I noticed a very close fight between Ruby and Rust as they are the second most favourite guest languages among Team PWC members. It is likely next week, we would have a clear winner. All Ruby and Rust contributors keep sharing solutions.

Last 5 weeks mainstream contribution stats. Thank you Team PWC for your support and encouragements.

Task 1: Lucky Integer

Submitted by: Mohammad Sajid Anwar

You are given an array of integers, @ints.

Write a script to find the lucky integer if found otherwise return -1. If there are more than one then return the largest.

A lucky integer is an integer that has a frequency in the array equal to its value.

Example 1

Input: @ints = (2, 2, 3, 4)
Output: 2

Example 2

Input: @ints = (1, 2, 2, 3, 3, 3)
Output: 3

Example 3

Input: @ints = (1, 1, 1, 3)
Output: -1

Task 2: Relative Sort

Submitted by: Mohammad Sajid Anwar

You are given two list of integers, @list1 and @list2. The elements in the @list2 are distinct and also in the @list1.

Write a script to sort the elements in the @list1 such that the relative order of items in @list1 is same as in the @list2. Elements that is missing in @list2 should be placed at the end of @list1 in ascending order.

Example 1

Input: @list1 = (2, 3, 9, 3, 1, 4, 6, 7, 2, 8, 5)
       @list2 = (2, 1, 4, 3, 5, 6)
Ouput: (2, 2, 1, 4, 3, 3, 5, 6, 7, 8, 9)

Example 2

Input: @list1 = (3, 3, 4, 6, 2, 4, 2, 1, 3)
       @list2 = (1, 3, 2)
Ouput: (1, 3, 3, 3, 2, 2, 4, 4, 6)

Example 3

Input: @list1 = (3, 0, 5, 0, 2, 1, 4, 1, 1)
       @list2 = (1, 0, 3, 2)
Ouput: (1, 1, 1, 0, 0, 3, 2, 4, 5)
