Replace string with array content in ruby?

Question

String = "Test string Test"
array = ["link1","link2"]

How can replace string like this ?

Output should be String = "link1 string link2"

String is a Ruby standard class name, and local variable should be in lowercase. — James Chen

String#gsub! could return an enumerator, so this is easy:

string.gsub!("Test").each_with_index { |v, i| array[i] }

you had written it with gsub earlier, why did u replace it with gsub!? It is always good to avoid gsub! as it modifies the original object.

I did that because from the question I thought krunal wanted the original string to be modified.
