Do these numbers add up?
This is a problem set. Some of these are easy, others are far more difficult. The purpose of these problems sets are:
- to build your skill applying computational thinking to a problem
- to assess your knowledge and skills of different programming practices
What is this problem set trying to do
I found this problem on Daily Coding Problem, a site you should sign up for so you can practice your problem sets
Given a list of numbers and a number k, return whether any two numbers from the list add up to k.
For example, given
[10, 15, 3, 7] and
10 + 7 is 17.

Can you do this in one pass?
How you will be assessed
Your solution will be graded using the following axis:
- To what extent does your code implement the features required by our specification?
- To what extent is there evidence of effort?
- To what extent did your code meet specifications?
- To what extent did your code meet unit tests?
- To what extent is your code free of bugs?
- To what extent is your code written well (i.e. clearly, efficiently, elegantly, and/or logically)?
- To what extent is your code eliminating repetition?
- To what extent is your code using functions appropriately?
- To what extent is your code readable?
- To what extent is your code commented?
- To what extent are your variables well named?
- To what extent do you adhere to style guide?
