1203. String repeat

Write a function that accepts an integer n and a string s as parameters, and returns a string of s repeated exactly n times.

Examples (input -> output)

6, "I"     -> "IIIIII"
5, "Hello" -> "HelloHelloHelloHelloHello"

Solution:

String repeatString(int n, String s) {
  String result = '';
  for (int i=0; i<n; i++) {
    result += s;
  }
  return result;
}

String repeatString(int n, String s) => s * n;
