The Weekly Challenge

09. TASK #1: Element Digit Sum

HEADLINES

Welcome to the Week #261 of The Weekly Challenge.

Just a quick update with regard to the work carried out by Outreachy Applicants, we now have new shiny homepage and new logo. We are working on new interactive user interface. We would have MySQL database for critical data. You can track the work in the repository if you want. We have only scratched the surface now. The actual work would begin when we convert the HTML page to Template page and start creating Dancer2 backed REST API.

If anyone wants to contribute, please get in touch with us.

Task 1: Element Digit Sum

Submitted by: Mohammad Sajid Anwar

You are given an array of integers, @ints.

Write a script to evaluate the absolute difference between element and digit sum of the given array.

Example 1

Input: @ints = (1,2,3,45)
Output: 36

Element Sum: 1 + 2 + 3 + 45 = 51
Digit Sum: 1 + 2 + 3 + 4 + 5 = 15
Absolute Difference: | 51 - 15 | = 36

Example 2

Input: @ints = (1,12,3)
Output: 9

Element Sum: 1 + 12 + 3 = 16
Digit Sum: 1 + 1 + 2 + 3 = 7
Absolute Difference: | 16 - 7 | = 9

Example 3

Input: @ints = (1,2,3,4)
Output: 0

Element Sum: 1 + 2 + 3 + 4 = 10
Digit Sum: 1 + 2 + 3 + 4 = 10
Absolute Difference: | 10 - 10 | = 0

Example 4

Input: @ints = (236, 416, 336, 350)
Output: 1296

Task 2: Multiply by Two

Submitted by: Mohammad Sajid Anwar

You are given an array of integers, @ints and an integer $start..

Write a script to do the followings:

a) Look for $start in the array @ints, if found multiply the number by 2
b) If not found stop the process otherwise repeat

In the end return the final value.

Example 1

Input: @ints = (5,3,6,1,12) and $start = 3
Output: 24

Step 1: 3 is in the array so 3 x 2 = 6
Step 2: 6 is in the array so 6 x 2 = 12
Step 3: 12 is in the array so 12 x 2 = 24

24 is not found in the array so return 24.

Example 2

Input: @ints = (1,2,4,3) and $start = 1
Output: 8

Step 1: 1 is in the array so 1 x 2 = 2
Step 2: 2 is in the array so 2 x 2 = 4
Step 3: 4 is in the array so 4 x 2 = 8

8 is not found in the array so return 8.

Example 3

Input: @ints = (5,6,7) and $start = 2
Output: 2

2 is not found in the array so return 2.

Last date to submit the solution 23:59 (UK Time) Sunday 24th March 2024.
