Write a function nexthour that receives one integer argument, which is an hour of the day, and returns the next hour. This assumes a 12-hour clock; so, for example, the next hour after 12 would be 1. Here are two examples of calling this function:

>> fprintf('The next hour will be %d.\n',nexthour(3))The next hour will be 4.>> fprintf('The next hour will be %d.\n',nexthour(12))The next hour will be 1.
