Question 1 Write an ARM assembly language program which implements a loop to calculate the integer division of two unsigned numbers stored in r2 and r1 (i.e., computes r2/r1), and store the result in rO. You can do this by counting successive subtractions of the divisor (r1) from the dividend (r2) until the difference is less than the divisor. Your code should not destroy the values of r1 or r2. Question2 Write ARM assembly language instructions to set the least significant byte of rO to zero if the least significant byte of rO is the same as the least significant byte of r1. Use registers r2 and r3 as scratch registers (to store intermediate values)
