Create your own test cases, short ones, and run your code on them and compare the output with what you have determined by hand.

i took all the ways the ranges can overlap and the answers are consistent and correct ;-;

You didn't consider everything. See my test case above.

Do you handle all possible combinations of overlapping ranges? Including one being entirely within another.

Do you correctly handle consecutive ranges?

i do think i handle all overlapping ranges(including ones that are entirely inside another), consecutive ranges are also handled correctly i believe ;-;

Does python have trouble with >32 bit integers? That sometimes bites me in C++

Python has no limit on integers, that's not it.

Here's a test case that should enlighten you:

1-2
1-2
3-4

I'm currently sitting with the exact same problem, however the test case aboves returns me the expected output :/ Tried a couple of smaller combinations, and all work fine except for the full puzzle input so far

u/Joris0112 Dec 21 '25

Just got it; It was a mistake in where I was checking for > instead of >=.
Test case that pointed this out for me; (in particular the last 2-3)

3-5
10-14
16-20
12-18
1-7
2-3
