How to extract multiple numbers from a string and assign to individual variables

Question

Lets say I have the string "first=53 second=65 third=82". How do I assign each value to variables x, y, z?

Edit: The words must match as well. With the + signs and exact number of spaces.

regexes need a pattern to look for. What is the pattern you're establishing here? first -> x, second -> y, third -> z? — Jonathan Mee, Feb 19 '15 at 20:00
@JonathanMee yes. I believe the regex is this: /^first=\d+\ssecond=\d+\sthird=\d+/ But not sure how to extract — rightDrop, Feb 19 '15 at 20:01

str = "first=53 second=65 third=82"
x, y, z = str.scan(/\d+/).map(&:to_i)

Thank you. However, not what I'm looking for. The words must match as well. With the + signs and exact number of spaces. I forgot to mention it in the question. – rightDrop Feb 19 '15 at 20:04
Can't think of any intelligent use for that. Anyway, if you already know where everything is in the string, just get it off the string index. `x, y, z = [str[6..7], str[16..17], str[25..26]].map(&:to_i)` – SHS Feb 19 '15 at 20:11
