Project Euler 第6题
The sum of the squares of the first ten natural numbers is,
12 + 22 + ... + 102 = 385
The square of the sum of the first ten natural numbers is,
(1 + 2 + ... + 10)2 = 552 = 3025
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.
哈哈,这个题目最最简单咯,一句话Python搞定。老外的自然数好像不包括0,我的理解,前100个自然数应该为[0,99]嘛。。
sum(range(101))**2-sum(i*i for i in range(101))
