Problem 313. Pythagorean perfect squares: find the square of the hypotenuse and the length of the other side
Given the square root of a square number, seed, and a range, n, find the square number, Z as well as the other side, y, the square root of a square number i.e. return the hypotenuse squared as well as the length of the other side. Note that n is the number of squares to search through starting with one.
HINT: Z = seed^2 + y^2 where Z = z^2, find Z first and then y.
Note that Z, seed^2 and y^2 are all perfect squares.
>> [z s] = findPerfectZ(3,6)
z = 25
s = 4
