Suppose we have 3 arrays A, B, and C, array As base address is in $S3, Bs base address is in $S4, Cs base address is in $S5. You can only use two temporal registers $t0 and $t1. Convert the following code into MIPS assembly language code. Suppose every array element occupies 1 word in MIPS (32 bits).

A[20] = B[0] + C[6] - 1;
