Can someone help me on codehs. its 7.1.5: initials. here is what your supposed to do Write a function called initials that will take a first and last name and return their initials using the following format:

initials("Tracy", "Turtle")
# => "T. T."
initials("Peter", "Parker")
# => "P. P."

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) { if (n == 0) return ""; if (n == 1) return "x"; return f(n/2) + f(n - n/2); } options: a) constant b) logarithmic c) linear d) linearithmic e)quadratic f)cubic g) exponential

What is a point-in-time measurement of system performance?
