# Rock-paper-scissors-lizard-Spock template

# The key idea of this program is to equate the strings

# "rock", "paper", "scissors", "lizard", "Spock" to numbers

# as follows:

# 0 - rock

# 1 - Spock

# 2 - paper

# 3 - lizard

# 4 - scissors

import random

# helper functions

# convert name to number using if/elif/else
