Find My Jeepney!

/*
4. Find My Jeepney!
I've lived in Cebu my entire life, and my main form of transportation has always been the Jeepney. Even then, I still don't know where some of the Jeepneys wait for their passengers. So instead of waiting for a solution, why not make my own? Introducing Find My Jeepney! An app that would tell you where a Jeepney waits for passengers just by inputting its number and letter! I'm interested in hiring you as the developer, but I'm not sure if you're the right fit. If you could make me a prototype right now then I'll hire you on the spot.

Locations:
12A - Carbon
12C - Panganiban
12F - Taboan
12G or 12I - Mabolo
12L - Labangon
13C - Talamban
14D - Capitol

Inputs
1. The jeepney's number
2. The jeepney's letter
