## Editorial for WC '15 Contest 1 J1 - Do You Know Your Woburn Colours?

**only**when stuck, and

**not to copy-paste code from it**. Please be respectful to the problem author and editorialist.

**Submitting an official solution before solving the problem yourself is a bannable offence.**

This is a straightforward task solved using an if..else statement. It tests the competitor's basic abilities in input/output, comparing strings, and simple logic. Given two of three strings in the set of `{"RED", "BLUE", "WHITE"}`

, we are to identify the other one that was not mentioned.

Initially, one may be tempted to try and code for every possible case of the input (there are combinations) by checking the two inputted strings against ways to choose exactly two of the three colours, taking into account the fact that order matters. This is a feasible way to do it. However, it leads to a solution that is more complicated than necessary. Every second matters in a timed contest, so the less code we have to write the better. To simplify the cases to only cases without added complexity, we can just check which colour *isn't* in the input. That is, if neither of the input strings compare equal to a particular colour, then this colour must be the one we output.
