I wanted to solve the project euler question sum square difference. My expected output is the difference between the sum of squares below 100 and the square of sums below 100

I don't understanding squires of sums below 100. Is it not like pow(1+2+3...+99 , 2)? Joseph Oritseweyinmi

Make input 101 and print sum2*sum2 -sum , problems asks what is the difference between (1+2+3...)**2 and 1+4+9+16+25...

￼  ￼￼ 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.
