An integer is said to be prime if it is divisible by only 1 and itself.
For example,2,3,5 and 7 are prime,but 4,6,8 and 9 are not.
a) Write a function that determines if a number is prime.
b) Use this function in a program that determines and prints all the prime
numbers between 1 and 10,000. How many of these 10,000 numbers do you
really have to test before being sure that you have found all the primes?

如果我們具有磁場，
則當我們每次經過電冰箱門的時候，
我們都可能會與冰箱門撞在一起，
所以人的身體不具有磁場是有其優點的。
