The Weekly Challenge

09. TASK #1: Unique Occurrences

HEADLINES

Welcome to the Week #260 of The Weekly Challenge.

Did I tell you that I submitted The Weekly Challenge project to the upcoming Outreachy Program sponsored by TPRF?

Well, it is first time for us. Last week, we started getting response from applicants of the program. They have already started working on the project. The plan is move the current static website to realtime interactive website. For this we are using Dancer2 web framework with MySQL as the database. For frontend we are using HTML, JavaScript and Bootstrap.

If you have any suggestion to improve the user experience then please do share with us.

Working with interns have been great so far. They are all full of energy and ready to take on challenge. I just guide them when they are stuck.

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

Task 1: Unique Occurrences

Submitted by: Mohammad Sajid Anwar

You are given an array of integers, @ints.

Write a script to return 1 if the number of occurrences of each value in the given array is unique or 0 otherwise.

Example 1

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

The number 1 occurred 3 times.
The number 2 occurred 2 times.
The number 3 occurred 1 time.

All occurrences are unique, therefore the output is 1.

Example 2

Input: @ints = (1,2,3)
Output: 0

Example 3

Input: @ints = (-2,0,1,-2,1,1,0,1,-2,9)
Output: 1

Task 2: Dictionary Rank

Submitted by: Mark Anderson

You are given a word, $word.

Write a script to compute the dictionary rank of the given word.

Example 1

Input: $word = 'CAT'
Output: 3

All possible combinations of the letters:
CAT, CTA, ATC, TCA, ACT, TAC

Arrange them in alphabetical order:
ACT, ATC, CAT, CTA, TAC, TCA

CAT is the 3rd in the list.
Therefore the dictionary rank of CAT is 3.

Example 2

Input: $word = 'GOOGLE'
Output: 88

Example 3

Input: $word = 'SECRET'
Output: 255

Last date to submit the solution 23:59 (UK Time) Sunday 17th March 2024.
