This is the first correct solution to this problem. It took 4.5 years and 500 wrong solutions for someone to finally get a universal answer.

Brandon submitted a Comment to Problem 52. What is the next step in Conway's Life?

There's a popular solution that is wrong, and people keep posting it. I am highly amused.

I made a solution explaining the three common approaches to solving the problem. All three solutions have a small Cody size, but have drastically different speeds when implemented in code.

It's a much faster implementation of num2str() than any other solution I have seen. Due to it formatting the inputs and using the second column, it avoids the searching problems that other num2str() solutions often have. This solution can be further optimized by avoiding the use of num2str() and calling sprintfc() directly.

Brandon submitted a Comment to Problem 47. Extract leading non-zero digit

Today I learned that 0.3/0.1 = 2.999999999 but 0.3*10=3 Floats always keep things... interesting...

How does this solution escape the floating point problem for x=0.3? raising to the negative power seems to be superior than dividing by the positive power?

A great example of slow code, this solution takes 4.5 seconds to run through 1000 random numbers. My solution takes a millisecond. Cody "size" is such a poor measure of good code...

Brandon submitted a Comment to Problem 48. Making change

A lot of people are adding an amount smaller than a cent to the input to get around floating point issues. There are two other ways to get around this. One is to make the last cent 0.00999 instead. The other is to change your comparison line to compare against a slightly smaller/larger value.

Could have reduced the 1 in a/change(i)>=1 to 0.999 as well.

Brandon submitted a Comment to Problem 9. Who Has the Most Change?

I have tagged this problem as stupid. I encourage others to do the same. This is a place to learn, not to ask trick questions.

Brandon submitted a Comment to Problem 9. Who Has the Most Change?

Can we ban stupid problems like this? Like, how do I report a problem to have it moderated out of existence?
