欧拉计划(python) problem 6 Sum square difference Problem 6

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.


Python code :

n=100
sum=0
for i in range(1,n):
for j in range(i+1,n+1):
sum+=2*i*j
print(sum)


result :25164150
