Problem 6:
What is the difference between the sum of the squares and the square of the sums?
#include
using namespace std;
int main() {
long long sum = 100*101/2;
long long sq_i_sum = 0;
for(int i =0; i<=5; i++){
sq_i_sum += i*i;
}
long long diff = sum*sum-sq_i_sum;
cout << "sum " << sum << " sq_i_sum " << sq_i_sum << " diff: " << diff;
return 0;
}
