Hey Chen! Great to hear about the Cody anniversary contest --- I've been having fun again solving Cody problems.
Turns out that there's an issue with the test suite for problem 42633 however that renders this problem unsolvable, and since the author has (apparently) not been active in months, perhaps you or someone else at MathWorks could take a look?
The issue is with the first test, which tries to ascertain that max() is not used in the solution using a simple text search for max, but which also trips on the fact that the function to be written is itself called cumax.
FWIW, without solving this problem you also can't solve the Matrix Manipulation III group and get that badge. So it would be great if you or someone could take a look and, perhaps, simply remove the problematic assertion from the first test case.
Thanks!
Hello Christian, I saw your comment on the problem as well. I will fix the problem as soon as it is possible for me to do so, meanwhile please solve other problems.

Hi Duyman, thanks a lot for the fix! I just noticed another issue: the test suite for problem 150 uses the chirp() function from the Signal Processing Toolbox, which is not available on Cody. As a result, this problem cannot be solved (without recreating chirp.m anyway).
try to add this optional FEX function, it says with red warning, correct File exchange URL needs to be used !! what did I do wrong whern I paste above strings in as URL.
Could you please let us know how to use file exchange functions? Thanks
@Chen, which timezone is followed to count on which day a problem was solved for the streak?
Correction: It's using UTC.
MathWorks should specify in the rules clearly or have a daily countdown next time, it's inconsistent w/the counter on the home page.
Sorry for the confusion and inconsistency issue. Daily countdown is a great idea.
Hi Dyuman. I'll discuss the feedback to the team.
Announcement:
Week 1 Problem Group for Cody 10th Anniversary Contest was just published!
Will you be the first 3 players to complete this chanllenge?
