I actually solved it using my solution. the problem was that i was erroneusly using pointers on slices. i studied more how golang passes slices and what's actually the "value" passed between functions. this would make an unstable behavior of the code. still i haven't figured out why locally it was constantly passing everything. solved by just removing pointers.

I really thank you for your quick responses. this was really a my bad.

You can try one (or all) of following:

• Post your code here so someone could check it (remember about code formatting and use Spoiler flag).
• Make sure that you use the same version of Go on your local machine and on Codewars (which is 1.20).
• Join Codewars Discord and post a question in #help-solve channel. It might be easier to find someone to help there.

i don't get it, i'm currently printing the solution with your tests, multiple times, i keep getting the right answer (9) locally. my code seems to keep working after changing the order of the inputs. could i share the code somehow without having
to spoiler others?

Your solution seems to not be correct, it behaves in a stange way for following test cases:

Expect(SumOfIntervals([][2]int{{1, 5}, {6, 11}})).To(Equal(9))  // your solution returns 5
Expect(SumOfIntervals([][2]int{{6, 11}, {1, 5}})).To(Equal(9))  // your solution returns 4

Your solution returns different answers for the same set of intervals, given in different order.

Your solution not passing tests is not a kata issue.

i feel like my code works fine, yet i cannot pass any test here. copied all the tests i saw in the comments and the onse in the problem details and it work for me. i don't get it, i don't have the problem of swapping the intervals. plus i printed the inputs and locally it still get the expected value. yet running it here won't work

No worries, best of luck with your other katas and solutions!

Yeah, it took reading over it 15 times, but i finally realised my mistake, Just a downside of dyslexia...

Are you 100% sure you've tested the edge case where the word length is equal to 5?

Yes, good catch! You can utilize 2 pointer technique for that, but since this kata does not focus much on optimziation and performance, most people will just go along with a more straightforward solutions which typically involve iterating through the string more than once :(
