Greatest Greatest Common Divisor Problem Description Andrew has just made a breakthrough in sociology...And the quality of friendship between two persons is equal to the greatest common divisor of their friendship...In other words, output the greatest greatest common divisor among all pairs of given friendship numbers
1、 == 号与 is 的区别：要知道 == 判断是的值，而 is 判断的是地址值。所以 "AAA" == "AAA" 结果是为 True
原理：（m,n）代表m和nGCD，和m>n。然后，(m,n)=(n,m%n)=…..直到余数为0.
当两个非负整数x和y都是0的时候，他们的最大公约数是0. 当两者至少有一个不是0的时候，他们的最大公约数是可以除尽二者的最大整数。 因此gcd(0,0)=0, ...
