终于不再是hello world

在跟rice大学的课程以及北京哈尔滨工业大学车万翔老师的课。有进步。记录一下 石头-布-剪刀-蜥蜴-史塔克

# 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


# helper functions
