Question
Please explain
![The Fibonacci sequence is defined as 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...
The first two terms, f[0) and f(1), are equal to 1. Every subsequent term is the sum of the
two
previous terms. Thus for each n≥2n22, we have f(n)=f(n-1)+f(n-2).
Here are two Python programs to calculate f(n)f(n). One of these two methods uses
bottom-up dynamic programming and one of these two methods uses recursion. But which
one is which?
def fib1(n):
if n<=1: return 1
else: return fib1(n-1)+fib1(n-2)
def fib2(n):
table [ for i in range(n+1)]
for i in range(n+1):
if i=1: table[i]=1
else: table[i]=table[i-1]+table[i-2]
return table[n]

To help me figure which algorithm is which, I decided to calculate fib1 (44) and fib2 (44)
and was shocked to discover that the running times were so different!
