Short Problem Definition:
There are N chocolates in a circle. Count the number of chocolates you will eat.
expected worst-case time complexity is
expected worst-case space complexity is
N and M meet at their least common multiply. Dividing this LCM by M gets the number of steps(chocolates) that can be eaten.
