  а) Cоnvert the fоllоwing C code into RISC-V аssembly code. Use only the operаtors listed in the Final Exam Formula section of this exam. Assume that a is stored in register t0 and b is stored in register t1. Comment each line of assembly code. (Hint: you can read the last digit of the binary format to check if the number is even or odd.)   if (a % 2 == 0)    a /= 2;else     a *= 2;if (b % 2 == 1)    b /= 4;else    b *= 4;    b) Convert the following ‘reverse’ function, which takes an integer array and its size asarguments and reverses the array in place, into RISC-V assembly code. It returns the address of thearray as a return value. Use only the operators listed in the Final Exam Formula section of this exam.Comment each line of assembly code. int *reverse(int arr[], int size){int start = 0;int end = size - 1;int temp;while (start < end){temp = arr[start];arr[start] = arr[end];arr[end] = temp;start++;end--;}return arr;} Use the following template reverse:# Save return addressaddi sp, sp, -16sw ra, 12(sp)# Initialize pointers# to do..loop:# Check if start < end# Load values# Swap values# Move pointers# to do.. c) Implement the following loop in RISC-V. Store sum in t0 and k in t1.  sum=0; for (int k = 100; k > 0; k--) {      sum+=k;       }
