There is a right triangle with legs of length *a* and *b*. Your task is to determine whether it is possible to locate the triangle on the plane in such a way that none of its sides is parallel to the coordinate axes. All the vertices must have integer coordinates. If there exists such a location, you have to output the appropriate coordinates of vertices.
The first line contains two integers *a*, *b* (1 ≤ *a*, *b* ≤ 1000), separated by a single space.
a, b = map(int, input().split())
s = [i*i for i in range(1, int(max(a, b)**0.5+1))]
for i in s:
    if a-i in s:
        for j in s:
            if b-j in s: print('YES'); exit()
        print('NO'); exit()
print('NO')
