1. [20%] Translate the following C code to the minimum MIPS assembly instructions
int A[20], B[20]；
i=0；
while (A[i]!=0 && i＜20){
B[i] = A[i]+B[A[i]]+i；
i++；
}
At the beginning of this code segment, the only values in registers are the base address of arrays A and B in registers $al and $a2. Assume that the value of i is stored in the register $t1.
