# Code for testing the reflex agent in homework 3.

# Add the function for the reflex agent called nlife_agent for the
# function bellow to work.

# A function that transforms a list by replacing every element with
# the result of the processing done by the reflex agent to be
# written. It doesn't change the original list but returns the result
# list instead.
def nlife (L):    
    result = []
    for i in range(len(L)):
        if i == 0:
            prev = 0
        else:
            prev = L[i-1]
        if i == len(L)-1:
            next = 0
        else:
            next = L[i+1]
        result.append(nlife_agent(prev, L[i], next))
    return result

# Test to make sure the function above works
#def nlife_agent(x, y, z):
#    return max(x, y, z)

# Creating a global list to test the function
testl = [1, 2, 3, 4]

# Calling this function should result in the list bellow.
nlife(testl)
#[0, 0, 1, 7]

# Executing the following instruction repeteadly should run the game
# of numerical life. The sequence of lists bellow is an example of the
# evolution of the original list through this process, shown backwards
# (it starts at the bottom going up).
