(Sign flag) SF

It is set if the most significant bit of the outcome, which is the sign bit of a signed integer. (0 shows a positive value and 1 shows a negative value.)

OF (Overflow flag)

It is set if the integer result is too big a positive number or too small a negative number to fit in the destination operand (excluding the sign-bit); otherwise cleared. This flag shows an overflow condition for the arithmetic signed-integer (complement of two).

Suppose that you have several numbered billiard balls on a pool table. The smallest possible number on the ball is “1”. At each step, you remove a billiard ball from the table. If the ball removed is numbered n, you replace it with n balls randomly numbered less than n. For example, if you remove the “5” ball, you replace it with balls numbered “2”, “1”, “1”, “4”, and “3”, where numbers 2, 1, 1, 4, and 3 were randomly...
