Ruby Programming Strings

Front 1

Split string "abc" - one character at a time.
Expected result = Array - e.g.:
["a", "b", "c"]

Back 1

"abc".split(//)
"abc".scan(/./)
"abc".chars.to_a

Front 2

Starting at 1, puts 1 to 10.

Back 2

1.upto(10) {|number| puts number}

Front 3

populate array starting with zero in step 6 (upto 100).

Back 3

a = 0.step(100, 6).to_a

Front 4

Give some example to String.scan method usage.
Note: scan returns all matches.

#match returns the first match as a MatchData object, which contains data held by special variables like $& (what was matched by the Regex; that's what's mapping to index 0), $1 (match 1), $2, etc

Back 4

a = "cruel world"
a.scan(/\w+/) #=> ["cruel", "world"]
a.scan(/.../) #=> ["cru", "el ", "wor"]
a.scan(/(..)(..)/) #=> [["cr", "ue"], ["l ", "wo"]]
