COP-3337 Programming II Programming Assignment 7 Knight Foundation School of Computing and Information Sciences In this assignment, you implement a simple calculator supporting integer values with only two operations addition and subtraction. The program receives an expression like 95 − (12 + 33) from the keyboard and prints out the result (50 in this case) on the screen. Please note that the input expression may include nested parentheses like 2 + (1 − (3 + ((4 − 1) + (12 − 6)))) Therefore, your program needs to use the stack data structure (like java.util.Stack) to store the intermediate results of inner parentheses and/or the operators. 1 Sample Input/Output Here are some examples of how your program should operate: input expression output ((2)) 2 −0022 −22 −(2 − 3 − 4) 5 (+34) 34 2 + (1 − (3 + ((4 − 1) + (12 − 6)))) −9 1 + (2 − (3 + 4 − (5 + (6 − (7 + (8 − 9)))))) 1 2 Submissions You need to submit a .zip file compressing the Java source file(s) of your program (.java files). 1
