Pythagorean Triples

Level: Easy

Three numbers form a Pythagorean triple if the sum of squares of two numbers is equal to the square of the third. 

 For example, 3, 5 and 4 form a Pythagorean triple, since 3*3 + 4*4 = 25 = 5*5 

You are given three integers, a, b, and c. They need not be given in increasing order. If they form a Pythagorean triple, then print "yes", otherwise, print "no". Please note that the output message is in small letters.
