Pairing is when two programmers work together on a problem. We do it a lot at DBC.
Since we'll be pairing with you, if you don't know something, like some fact or detail, that's fine. You should really focus on how to think and talk about the challenge (the technical problem), ie. how to explain what you're thinking, follow what we do together and talk about it, and be able to recognize when we've succeeded!
Most of all just try to relax and enjoy working with us through this process.
We have been contracted to write a piece of software for a restaurant. They want to easily be able to enter orders that come in, and be told how long the wait time will be for that order. That is, we are going to write a simple program for placing an order at a restaurant and it will print to the screen how long the wait is.
You can order the following items:
| def leap_year?(year) | |
| if year % 4 == 0 | |
| puts "I am divisible by 4!" | |
| true | |
| elsif year % 100 == 0 | |
| puts "I am divisible by 100!" | |
| false | |
| elsif year % 100 == 0 && year % 400 == 0 | |
| puts "I am divisible by 100 and 400!" | |
| true |
| def valid_triangle?(a, b, c) | |
| if ((a == 0 or b == 0 or c == 0) or (a == nil or b == nil or c == nil)) | |
| return false | |
| end | |
| if a + b > c | |
| puts "case 1" | |
| return true |
