Pyth - 19
qS@cz", "0S@cz", "1
Try it here. Note that the two words in the input must be separated by a comma and a space.
Python Mapping and explanation
q # equal( "Check equality"
S # sorted( "Sort"
@ # list looku "Extract element from list"
c # chop( "Separate by delimiter"
z # input( "Input variable"
", " # ", " "This delimiter"
0 # 0 "The 0th element"
S@cz", "1 # .. "The same thing with the 1st element
I'm sure someone can come up with a shorter implementation, but I've only been learning Pyth for a few days. It would also be a lot shorter if I didn't stick strictly to the input format given in the question.
For instance:
qS@Q0S@Q1
Which is only 9 bytes, works if the input is formatted like 'parse','spare'. So which one do you count?
Good practice though!
