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[edit]
In this example we are learning about lists, iteration, and conditionals.
The Problem[edit]
I found this problem on Daily Coding Problem, a site you should sign up for so you can practice your problem sets[2]
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 k
of 17
, return true
since 10 + 7 is 17
.
Hacker edition[edit]
In the hacker version:
Can you do this in one pass?
How you will be assessed[edit]
Your solution will be graded using the following axis:
Scope
- To what extent does your code implement the features required by our specification?
- To what extent is there evidence of effort?
Correctness
- 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?
Design
- 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?
Style
- 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?

#Filip
list = [10, 15, 3, 7]
k = 22
def add_up(list, k):
fit = False
for a in list:
for x in range(len(list)):
if a+list[x] == k:
fit = True
return fit
print(add_up(list, k))
