2. Assume that the variables f, g, h, i, and jare assigned to registers x5, x6, x7, x28, x29 respectively. Assume base address in memory of Array data structures 'A, B, C' (or address in memory of 'A [0]', 'B[0]' and 'C[0]') are stored in Registers x27, x30, x31. Write RISCV code that implements: (a) A[i] = B[2i+1], C[i] = B[21] (b) A[i] =2B [i-1] + 4C [i+1]
