In the following questions assume the variables a and b are signed integers and that the machine
uses two's complement representation. also assume that max int is the maximum integer, min int
is the minimum integer, and w is one less than the word length (e. g., w = 31 for 32-bit integers).
match each of the descriptions on the left with a line of code on the right (write in the letter).
