(C) How many additional spaces will be reserved for the operand stack by the Java Compiler assuming that "Math.sqrt((b* b)-(4 * a * ))" is the most complicated expression in the findRoots method given above? Show clearly how you arrived at this answer. Note: You can ignore the assignment (=) while computing the operand stack spaces.
