The Weekly Challenge

HEADLINES

Welcome to the Week #285 of The Weekly Challenge.

First thing first, today is the first Monday of the month and time to declare the next champion. With great pleasure, I announce Mariano Ortega as the next Champion of the Month. He is fairly new addition to Team PWC. He joined the team in the Week #277. As of today he shared 14 solutions in Perl. I will send you email with regard to the prize money, please keep an eye in your mailbox and respond asap.

Just a gentle reminder to Andrew Schneider, I am still waiting for your response to my email dated 5th Aug 2024 with regard to prize money. Please reply when you get time.

Let us all welcome two new Perl hackers, Torgny Lyon and Tim King. With this we now have 315 members and of those, 17 never contributed even once.

Thank you, Peter Meszaros, for still carrying on dealing with past challenges in Perl.

Thank you, Paulo Custodio, for finally getting done with all the past challenges in Perl. Right now, I noticed you are dealing with them in Python. Good luck and all the very best.

I also noticed handy scripts shared by Paulo. I would suggest you take a closer look e.g. [stats.pl] | [check_challenge_title.pl] | [go.pl] | [test.pl].

Welcome back, Andrezgz and thanks for sharing solutions to Week #283 in Perl.

Task 1: No Connection

Submitted by: Mohammad Sajid Anwar

You are given a list of routes, @routes.

Write a script to find the destination with no further outgoing connection.

Example 1

Input: @routes = (["B","C"], ["D","B"], ["C","A"])
Output: "A"

"D" -> "B" -> "C" -> "A".
"B" -> "C" -> "A".
"C" -> "A".
"A".

Example 2

Input: @routes = (["A","Z"])
Output: "Z"

Task 2: Making Change

Submitted by: David Ferrone

Compute the number of ways to make change for given amount in cents. By using the coins e.g. Penny, Nickel, Dime, Quarter and Half-dollar, in how many distinct ways can the total value equal to the given amount? Order of coin selection does not matter.

A penny (P) is equal to 1 cent.
A nickel (N) is equal to 5 cents.
A dime (D) is equal to 10 cents.
A quarter (Q) is equal to 25 cents.
A half-dollar (HD) is equal to 50 cents.

Example 1

Input: $amount = 9
Ouput: 2

1: 9P
2: N + 4P

Example 2

Input: $amount = 15
Ouput: 6

1: D + 5P
2: D + N
3: 3N
4: 2N + 5P
5: N + 10P
6: 15P

Example 3

Input: $amount = 100
Ouput: 292

Last date to submit the solution 23:59 (UK Time) Sunday 8th September 2024.
