# Java solution to Project Euler Problem 6

The sum of the squares of the first ten natural numbers is,
1^2 + 2^2 + … + 10^2 = 385

The square of the sum of the first ten natural numbers is,
(1 + 2 + … + 10)^2 = 55^2 = 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.

Assessment: I exhibited symptoms of brain inversion the first time I read the problem description. I was very tired when I wrote this. How do I know? There are zombies in my code. ## 1 thought on “Java solution to Project Euler Problem 6”

solution in java for project euler problem 6

public class problem6
{
public static void main(String args[])
{
int total = 0;
int tot=0;
int diff=0;
for (int i = 1; i <= 100; i++)
{
total += (i*i);
tot+=i;
diff=(tot*tot)-total;

}
System.out.println("sum_squares() = " + total);
System.out.println("squares_sum() = " + tot);
System.out.println("difference= " + diff);

}
