'I nililai e ilu, following C eode i o MIPS :ritannlly et Kle. Nillne that the valles of a aud j are ill rypim; $s0 and $s1, respectively. Also, assume that register $s2 holds the base address of the array D. Assume that you want to use register $s3 to store the constant 10. for(1-0; 1 < 10 ; 1++){ j=0; while ( j < a ) D[j] = 1 + j + D[j];
