Question 11 (1 point)

The following function returns a string of length N whose characters are all 'x'. Give the order of growth (as a function of N) of the running time.

Recall that concatenating two strings in Java takes time proportional to the sum of their lengths.

 public static String f(int N) { String s = ""; for (int i = 0; i < N; i++) s = s + "x"; return s; }
