Figure 3 shows a subroutine written in pseudocode that calculates the sum of all positive numbers in an array.
SUBROUTINE computeTotal(numbers)
s ← 0
i ← 0
WHILE i < LENGTH(numbers)
IF numbers[i] > 0 THEN
s ← s + numbers[i]
ENDIF
i ← i + 1
ENDWHILE
RETURN s
ENDSUBROUTINE
The identifier for the variable s in Figure 3 was not a good choice.
State a better identifier for this variable that makes the algorithm easier to read and understand.
