Part 2

# 1. Let P1 be player one's score
# 2. Let P2 be player two's score
# 3. If P1 < 4 and P2 < 4, return 0
# 4. If P1 - P2 >= 2, return 1
# 5. If P2 - P1 >= 2, return 2
# 6. return 0

Part 3

# 1. Let S be sum
# 2. Let N be number of elements
# 3. While the user types in a number N
# 4.     S = S + N
# 5.     N = N + 1
# 6. if N > 0: return S/N
