Question

Transcribed Image Text:We define the following recursive Python function:
def cool (n):
if n==0: return 2
if n==1: return 1
return cool(n-1)+2*cool(n-2)
where n is assumed to be a natural number. Change the cool function into a dynamic
programming one:
def coolDP (n)
using memoisation. Note that you can use Python dictionaries for this function.

- Need some help with this c++ problem In order to compute a power of two, you can take the next-lower power and double it. For example, if you want to compute 211 and you know that 210 = 1024, then 211 = 2 × 1024 = 2048. Based on this observation, write a recursive function int pow2(int n) where n is the exponent.
