+## Why Ruby?
+
+Solving problems in Ruby can be a lot more fun than it first appears.
+Although it is a relatively simple programming language that does not require manual memory manipulation,
+it is also a relatively slow language.
+Sub-optimal C or Rust solutions will pass all tests,
+but Ruby or Python solutions will not be able to meet the time limit.
+This forces us to look for optimized algorithms.
