Hint:
  • initialize a variable to the identity element for the operation you are using with respect to the field or group that you are calculating over
  • loop over all elements of the array
  • inside the loop, replace the variable with OPERATION applied between the variable and the loop value
  • at the end of the loop, the variable holds the answer.
