Question: Consider the following recursive procedure. BLA(n): if n = 1 then return 1 else return BLA(n 1) + BLA(n 1) + BLA(n

Consider the following recursive procedure.

BLA(n): if n = 1 then return 1

else return BLA(n — 1) + BLA(n — 1) + BLA(n — 1)

(a) What function of n does BLA compute?

(b) What is the running time T(n) of BLA?

(c) How do the answers to (a) and (b) change if we replace the last line by "else return 3 . BLA(n — 1)"?
