Ruby String To Array Split

A string object holds and manipulates an arbitrary sequence of bytes typically representing characters.

Ruby string to array split.

Values each do v number integer v display number if it is greater than or equal to 200. String objects may be created using new or as literals. Typically methods with names ending in modify their receiver while those without a return. It will remove nothing at all from the original string and split on every character.

Ruby program that uses split parses integers line 100 200 300 split on the comma char.
