Write a function called multiplyString() that will receive a string and a number and return a string consisting of the given number of copies concatenated.
For example, if "cat" and 4 are passed in, your function should return the string "catcatcatcat".
Examples:
multiplyString("cat", 4) returns "catcatcatcat"multiplyString("cat", 1) returns "cat"multiplyString("x", 7) returns "xxxxxxx"multiplyString("schwifty", 0) returns ""©2017 Graham Mitchell
