Euler's plan (python) problem 6
Sum square differenceProblem 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
