8.14 Suppose A is a 10 x 10 array of (4-byte) integers, indexed from [0][0] through [9][9]. Suppose further that the address of A is currently in register r1, the value of integer i is currently in register r2, and the value of integer i is currently in register r3. Give pseudo-assembly language for a code sequence that will load the value of A[i]li] into register rl (a) assuming that A is implemented using (row-major) contiguous allocation; (b) assuming that A is implemented using row pointers. Each line of your pseudocode should correspond to a single instruction on a typical modern machine. You may use as many registers as you need. You need not preserve the values in r1, r2, and r3. You may assume that i and jare in bounds, and that addresses are 4 bytes long. Which code sequence is likely to be faster? Why?
