Dyuman Joshi submitted a Comment to Problem 60735. Delete some elements in the natural set and find the sum of the first n terms

The problem statement you have posted is not clear nor is there a test suite to work through/with. I suggest you to update your question accordingly within 1 week. Otherwise it will be deleted.

Though this function is considered slower for larger matrices, but since we are only dealing with vectors here, I assume it is good. Though I will run some tests to see how good it actually is. Of course, the best function to employ here is the one that just changes the header/flag of the array and not the data stored in the array. Though I was unable to find how to utilize it here. And I wonder how the Leading solution will fare against vectors with a big number of elements.

Note that using (:) is comparative slower - Here's an excellent thread dissecting why that is the case :- https://in.mathworks.com/matlabcentral/answers/887219-why-is-x-so-much-slower-than-reshape-x-n-1-with-complex-arrays?s_tid=srchtitle

Dyuman Joshi submitted a Comment to Problem 60734. Conditional transpose

Christian, I would suggest you to update the check for if condition statement to 'if ' (i.e. with a space at the end), as there are functions containing the string 'if' , which are allowed, but fail with the current anti-cheat test suite. Same for problem #60736. Conditional transpose II.

@Eric, thanks for highlighting. This solution will be deleted soon. If you see other such hacks, kindly flag the solution - Moderators and Cody team will take care of them.

Dyuman Joshi submitted a Comment to Problem 6. Select every other element of a vector

@Muhammad, take a deeper look at what the test cases are testing for.

Dyuman Joshi submitted a Comment to Problem 563. How to add?

@赵思铭, Cody only supports basic MATLAB. It does not support any Toolboxes. Thus, you can't use 'sym' which is a part of the Symbolic Math Toolbox. This is officially mentioned in the "Notes" section on this page - https://in.mathworks.com/matlabcentral/content/cody/about.html

I have changed my mind, arrayfun() and other similar functions are not allowed. @Tim, you might want to solve the problem again.

Dyuman Joshi submitted a Comment to Problem 60729. Organic Chemistry

A problem that requires hard-coded solution along with a limited test suite is not a good problem IMO.

Making a sophisticated test suite for such case(s) seems to be an interesting challenge!

Test suite has been updated and this solutions has been rescored. Also link to the wikipedia article has been fixed.

More of a pen and paper approach.

Not a good solution.

Dyuman Joshi submitted a Comment to Solution 4313625

@Eshita, this is a hack used to hide the actual code behind regexp(), and solve the questions with a fixed size (as per cody testing norms). regexp() hacks are not allowed in cody. Please flag any solution that uses it, so that mods can clean it up.

Dyuman Joshi submitted a Comment to Problem 1089. Create a random vector of integers with given sum

@Sunil, there is no constraint on the length of the vector. It can be anything, as long it satisfies the conditions specified in the problem description and the test suite.
