Have you tried stepping the code and checking the variable values and determine why it's not working? Also i don't see you ever incrementing the Variable "K"

first of all try to debug your code with using breakpoints in line # for example 172 or others, in this way you will see how your parameters really act in your code, so you will see the K value has no change in the code...
I hope you will find the problem source.

There is nothing that you've posted that will cause an "unreachable code detected" error.

The only problem I can see is the same that other people have mentioned; the loop controlled by K will never exit because K is never updated.
