Hi, first of all thanks, my code has now passed.

Have another Q. Forgive me if I am wrong but I thought breaks were used so that when the correct case is found it breaks out of the switch, therefore saving memory. With my line of thinking, why would it continue to more 1's to n when the other cases don't meet the criteria.

You didn't break each case in the switch. Meaning that when the code meets n, your code increment north, south, west, and east. This shouldn't happen, obviously.

Like this code, after 6 months of operation Java only just learned that a + sign next to a primitive turns it into a String!

Your code fails to address this --> There are no fractions of people. At the end of each year, the population count is an integer: 252.8 people round down to 252 persons.

Please use appropriate markdown formatting when posting code.

Is the test broken?

No.

When you're unsure, please use the Question label instead of the Issue label as the latter is for provable kata issues. See https://docs.codewars.com/training/troubleshooting#post-discourse.

I'm not sure my solution works? and why did it work when I set the temp variable to one in the min function and not when I set it to 0?
