*using python

1. Write a function copy(s, n) that takes as inputs a string s and an integer n, and that uses recursion to create and return a string in which n copies of s have been concatenated together. To force you to use recursion, you may not use the multiplication operator (*). Rather, you should use recursion to add together n copies of s. For example, 'hello'*3 is equivalent to 'hello'+'hello'+'hello', and you will need to use recursion to compute that sum. If n is less than or equal to 0, the function should return the empty string (i.e., the string ", which does not have any spaces between the quotes). Here are some test cases: >copyC'da', 2) dada >print(copyC' da', 2)) dada copyC'Go BU!', 4) copy('hello', 1) copyC'hello', 0) >>> copy( 'hello', -7) Go BU!Go BU!Go BU!Go BU!' hello
