Method Detail

solve

public java.lang.String solve()

Since a + b + c = 1000 has to be true, this method runs two nested loops. The outer loop from a = 1 to 999 and the inner one from b = a to 999. c is calculated as 1000 - a - b and the triplet is checked to be an Pythagorean.

Returns:

the product of the Pythagorean triplet
