1. Find the big−O, big−Ω estimate for x7y3+x5y5+x3y7. [Hint:
Big-O, big- Θ, and big-Omega notation can be extended to functions
in more than one variable. For example, the statement f(x, y) is
O(g(x, y)) means that there exist constants C, k1, and k2 such
that|f(x, y)|≤C|g(x, y)|whenever x > k1 and y > k2]
2. Find a div b and a mod b when:
(a) a = 30303, b = 333
(b) a = −765432, b = 3827
