Question: 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

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
