Perl Weekly Challenge 226

17 Jul, 2023

After a long hiatus from the Perl Weekly Challenges, I found a bit of respite in week to pull one through. It is only for the first task, as I didn't have to invest too many neurons when I read it during my flight. Therefore, I chose Ruby to solve it this time, since I am currently on a Ruby project, and the language solves in near "english-sentence" time (lol). [See Task 1]:

def main(s, indices)
 raise "Error: Length of the arguments do not match!" unless s.length == indices.length

  hash = indices.zip(s.chars).to_h
  result = hash.sort_by { |k, v| k }.map { |v| v[1] }
  result.join
end

This solution is doggone near self-explanatory:

• Raise an error if the lengths of the strings do not match
• Build a "hash/map/dict" by ziping the string's chars
• Take the hash; sort it by its key and pull the value out
• Assign the expression's result to ... result (lol)
• Join the entire thing together into a string

I miss doing these challenges. Perhaps, I'll get cracking on [Task 2] sometime this week. I may even catch up and do it all in Ruby and NodeJS (*since those are the tools I'm currently using for a client ;))

Happy hacking!
