Question
Please help me with this Principles of programming language homework question
![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 j is currently in register r3.
Give pseudo-assembly language for a code sequence that will load the value of A[i][j] into register
rl (a) assuming that
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?](https://content.bartleby.com/qna-images/question/e8f98c03-2dea-45fe-9e7d-c001811b98bd/3f6f514a-3a06-4222-9160-e428f90b61c2/pcpujpr_thumbnail.jpeg)
