We need to get some things calculated, so let's get to work.
Hit the problem endpoint and grab the image URL. The image will be a few lines of numbers and operations that you need to perform. Start with
0, go from top to bottom and figure out the final result. Careful! The numbers may get big. Make sure nothing overflows along the way.
To illustrate, an image roughly equivalent to:
+ 12 - 10 × 2
Should be treated as
(((0 + 12) - 10) × 2) which equals
A word on division: for
÷, the challenge uses floor division which may be slightly surprising. Floor division means that after dividing the numbers, the result is rounded down. This means that
-10 ÷ 3 is equal
-4)! Keep this quirk in mind.
Submit the final result the the solution endpoint. It's done!
image_url: the URL of the image we want you to process
Solution JSON structure:
result: the result of all the math
It's always interesting to make a computer really read things.
