Pipeline

As part of a data processing pipeline, complete the implementation of the make_pipeline method:

  • The make_pipeline method should accept a variable number of functions, and it should return a new function that accepts one parameter $arg.
  • The returned function should call the first function in make_pipeline with the parameter $arg, and call the second function with the result of the first function.
  • The returned function should continue calling each function in make_pipeline in order, following the same pattern, and return the value from the last function.

For example, calling make_pipeline(function($x) { return $x * 3; }, function($x) { return $x + 1; }, function($x) { return $x / 2; }), and then calling the returned function with 3 should return 5.

Not really. I was surprised to discover that many experts...
