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

Consider the following statements, then select one of the answers below: the signal() function shown below registers "sig_handler()" as the signal handler function for the sigkill signal, without the complexity of using when the sigkill signal is sent to a process running this code, by a user typing "kill -kill ", where the correct process id is used for to target the process, sig_handler() will be executed.
