Write a function join_with(words, separator) that returns the strings in list words joined together using separator between each one (mirroring how print(*words, sep=separator) would display them, but returned as a string rather than printed).

Examples

'red - green - blue'

Explanation

Elements joined with " - " between them.

Example 2

Input

join_with(["a"], ",")

Output

'a'
