Carry out resulting from addition of unsigned numbers can be used to check if the result of addition is incorrect. Write the shortest sequence of MIPS instructions to determine if there is a carry out from the addition of two registers St1 and St2. Place the carry out (0 or 1) in register $10. 4. Write a MIPS assembly program that asks the user to enter an integer, reads the integer and then displays the integer representation in both binary and hexadecimal, assuming 32-bit representation. A sample execution of the program is given below: Example: Enter an integer: -5 Number representation in binary is: 1111111|||||||||||||||||||1111011 Number representation in hexadecimal is: FFFFFFFB 1.
