The following problems deal with translating from C to MIPS. Assume that the variables f, g, h, i, and j are assigned to registers $s0, $s1, $s2, $s3, and $s4, respectively. Assume that the base address of the arrays A and B are in registers $s6 and $s7, respectively. Assume that the elements of the arrays A and B are 4-byte words:

For the C statements above, how many registers are needed to carry out the C statement using MIPS assembly code?

a. ff A[2]; b. B[8] = A[i] + A[j];
