Hello Andrei,
Consider:byte c = a | b; Say you already know min_a, max_a, min_b, and max_b. How do you compute min_c and max_c? I thought of it for a bit and it seems quite tricky.
x_bit_max == "the largest bit in x_max ^ x_min" x_oth_max == x_bit_max - 1;c_max = max(a_bit_max | b_oth_max, b_bit_max | a_oth_max) | (a_max & ~(a_bit_max | a_oth_max));
