String To Array Ruby Split

Because of aliasing issues users of strings should be aware of the methods that modify the contents of a string object.

String to array ruby split.

Values each do v number integer v display number if it is greater than or equal to 200. String objects in ruby have a method called split it is similar to the split function of perl it can cut up a string into pieces along a pre defined string or regex returning an array of smaller strings.

So if you want to split on n you need to change your code to use double quotes split n. This essentially turns the string into an array of equal length containing only one character strings one for each character in the string. It will remove nothing at all from the original string and split on every character.

In this case n is actually equivalent to n. If an empty string is used as the separator the string is split between each character. If the delimiter passed to string split is a zero length string or regular expression then string split will act a bit differently.
