I have following sveral arrays which each of them consists into a String.
x = ["t", "o", "d", "a", "y"]
y = ["i", "s"]
z = ["s", "u", "n", "d", "a", "y"]
my output should be like following:
x = [today]
y = [is]
Z = [sunday]
in together: today is sunday
How can i get expected array using ruby?
You will want to use the #join(separator) method.
See the official ruby docs for Array#join
Example:
['h', 'e', 'l', 'l', 'o'].join('')
=> "hello"
A good place to start learning the basics of Ruby is at Code Academy.
I also recommend dash for browsing documentation offline!
For final your output,
[x, y, z].map(&:join).join(' ')
You can use the .join() method like this:
x = ["t", "o", "d", "a", "y"]
y = ["i", "s"]
z = ["s", "u", "n", "d", "a", "y"]
x.join()
=> "today"
y.join()
=> "is"
z.join()
=> "sunday"
Then do this:
x.join + y.join + z.join()
=> "todayissunday"
Or combine x, y, z into one array and call join on it, like this:
Array(x + y + z).join
=> "todayissunday"
todayin[today]– a string? Then it should be["today"].
