I Am Very Excited!!!!!!!#

Write a function exclaim that takes a string and a integer, and produces that string with a number of exclamation marks after it equal to the given integer. You only need to consider cases where the number is 0 or greater (no negative numbers).

For example, exclaim("Hey", 4) should produce "Hey!!!!"

Hint: An interesting trick with Python strings is that you can multiply a string by a number to replicate the string that many times. For example:

>>> "na" * 4
'nananana'

Sample Input 1:

Hey 4

Sample Output 1:

Hey!!!!

Sample Input 2:

Hey 0

Sample Output 2:

Hey

Sample Input 3:

! 2

Sample Output 3:

!!!

Sample Input 4:

Ah 1

Sample Output 4:

Ah!
