As you know, `The Weekly Challenge`

, primarily focus on **Perl** and **Raku**. During the **Week #018**, we received solutions to **“The Weekly Challenge - 018”** by `Orestis Zekai`

in **Python**. It was pleasant surprise to receive solutions in something other than **Perl** and **Raku**. Ever since regular team members also started contributing in other languages like **APL**, **Awk**, **Bash**, **Bc**, **C**, **C++**, **Clojure**, **Elm**, **Erlang**, **Gembase**, **GNAT**, **Go**, **Haskell**, **HTML**, **Idris**, **Java**, **Javascript**, **Kotlin**, **Lisp**, **Lua**, **Node**, **OCaml**, **PHP**, **Python**, **Postscript**, **Prolog**, **R**, **Ruby**, **Rust**, **Scala**, **SQL**, **Swift**, **Tcl** and **XSLT**.
