return True
def primeList(n):
primes = []
for i in range(2,n):
if isPrime(i):

I have this massive array of ints from 0-4 in this triangle. I am trying to learn dynamic programming with Ruby and would like some assistance in calculating the number of paths in the triangle that meet three criterion:
You must start at one of the zero points in the row with 70 elements.
Your…
