Question $2$: For the following MIPS code to swap $2$ consecutive elements in an array, identify the

mistakes and correct them. Base address, A and index, i are in registers $s$0$ and $s$1,$ respectively.

Line$1$: sll $t$0,$ $s$0,$ $$2$

Line$2$: add $t$0,$ $t$0,$ $s$1$

Line$3$: lw $t$0,0($$t$1)$

Line$4$: lw $t$0,4($$t$2)$

Line$5$: sw $t$0,4($$t$1)$

Line$6$: sw $t$0,0($$t$1)$
