In the program below, the function subTotal receives an integer array inputarr as an argument, returns an array arr in which the sum of all elements of original array inputarr up to that location is stored in the same location. Which of the following is the correct combination of pieces of code to be inserted into [A] and [B] in the program? Here, the size of the array inputarr is greater than 1, elements outside the bounds of the array must not be accessed, and the array index starts at 1. [Program] O integer []:subTotal(integer []: inputarr) integer: i integer: n <- the number of elements in inputarr integer []: arr <- {0, ..., 0} // Number of elements is n. arr[1] <- inputarr[1] for (increase i from [A] to n by 1) arr[i] <- inputarr[i] + [B] endfor return arr
