Php interview questions Monkey King Algorithm

* Descript: an arithmetic to a program
* Program:
A group of monkeys are arranged in a circle and numbered by 1, 2,... and n.
Then start from 1st, count to m, and kick it out of the circle,
Start counting after it, count to m, and kick it out ...,
The monkey is called the King until there is only one monkey.
Programming to simulate this process, input m, n, and output the number of the last king.
