Problem 9

A Pythagorean triplet is a set of three natural numbers, a b c, for which,

a² + b² = c²

For example, 3² + 4² = 9 + 16 = 25 = 5².

There exists exactly one Pythagorean triplet for which a + b + c = 1000.
Find the product abc.

Solution

exit = false

for a in 1..999 do

    for b in a..999 do

        c = 1000 – a – b

        if c < b  then break end

         if a**2 + b**2 == c**2

            puts a*b*c

            exit = true

            break

         end

    end

    if exit then break end

end
