Problem 6：Sum square difference

The sum of the squares of the first ten natural numbers is:

                                 

The square of the sum of the first ten natural numbers is:

                             

Hence the difference between the sum of the squares of the first ten natural numbers and the square of the sum is 3025 − 385 = 2640. Find the difference between the sum of the squares of the first one hundred natural numbers and the square of the sum.

思路：

这题的话编程相对要简单一些，据题意已知1到10的和方差的求法，让我们求1到100的和方差，我们可以直接调用求和函数，大大的提高了我们编程的效率，好了，直接上代码。

n = input('varible= ')  %将输入变量赋值给n
i = 1 : n
x = sum(i.^(2));
y = sum(i).^2;
t = y - x;
t

结果： 25164150

短短几行代码就解决了问题，编程确实提升了我们的工作效率！大家多多交流！
