Sanzhar Askaruly submitted a Comment to Problem 68. Kaprekar Steps For those confused with test cases 2,3 and 5, like myself before, do conversion to 4-digit integer. Here is an example:
x = 1:
1000-0001 = 999
9990-0999 = 8991
9981-1899 = 8082
8820-0288 = 8532
8532-2358 = 6174
Therefore, y_correct = 5

Christian Schröder submitted a Comment to Problem 3092. Return fibonacci sequence do not use loop and condition Eh. I can see what you're going for here, but I really think these heavily-restricted problems aren't very relevant for anything practical. If you're tasked with implementing a solution to a particular problem, such things as running time, memory consumption and numerical stability may well be on your mind, but not using anything from a long list of basic control structures and functions... not so much.

Evan submitted a Comment to Solution 1877072 Due to the use of persistent variables and the conditional statements used, this solution would fail if the test suite were modified to include two tests in a row with the same increment value.

Piotr Lesniewski submitted a Comment to Problem 1517. Put m balls into n boxes (again) I'm not sure what is the point of eliminating 'ifs'? At any rate they can be easily replaced by e.g. 'while' loops, so in my opinion you should either eliminate both of them or none.

Ned Gulley submitted a Comment to Solution 1868534 Here's one way you can use cellfun to solve this problem. I made an anonymous function called isDraw.
isDraw = @(letter) letter=='D'
d = cellfun(isDraw,games)
draws = sum(d)

Christian Schröder submitted a Comment to Problem 796. Removing rows from a matrix is easy - but what about inserting rows? Nice problem, but the specification could be improved: from the description, you'd think the entire matrix b is supposed to be inserted after each row in IND; it's only the first example that makes it clear that this is not the case.
