please answer according to the question with explanation

a) Write a fuction (inirilmun rumber of instructions) that accepts two pararneters: the array address of integer elernerits in reghter sao and its ste (even vahe) in reghster Sat. The furnction should arrange the elements in every pair in the array in the function code without using stack frames. Beiow, you can see the hily version of the function. waid furncrint arrit int sire) f Int E for (int j=0-sisicje-2) 1 if (arr0parr[f+1] [t-arritt arri]=arr[t+1) arr[t+1] =t ) Use the following function heading func : $a0= Rart. Fa1 size ) Ghen the following array definition: x2: word 5,6,-20,8, ... 60 \# 32 elements Write the needed MIPS instructions to call the above-defined function
