Your program will take an arithmetic expression as a String input. For Example:

 

  • “1+2*(3/4)”

 

  • “1+2*[3*3+{4–5(6(7/8/9)+10)–11+(12*8)]+14”

 

  • “1+2*[3*3+{4–5(6(7/8/9)+10)}–11+(12*8)/{13+13}]+14”

 

Program

 

Your program will determine whether the open brackets (the square brackets, curly braces and the parentheses) are closed in the correct order.

 

Outputs:

 

Output 1

 

1+2*(3/4)

This expression is correct.

 

Output 2

 

1+2*[3*3+{4–5(6(7/8/9)+10)–11+(12*8)]+14

This expression is NOT correct.

Error at character # 10. ‘{‘- not closed.

 

Output 3

 

1+2*[3*3+{4–5(6(7/8/9)+10)}–11+(12*8)/{13+13}]+14

This expression is correct.

 

Output 4

 

1+2]*[3*3+{4–5(6(7/8/9)+10)–11+(12*8)]+14

This expression is NOT correct.

Error at character # 4. ‘]‘- not opened.

Task 1

Solve the above problem using an array-based stack.

 

Task 2

Solve the above problem using a linked list-based stack.

  1. Complete the following problem using concepts of STACK.
  2. If you are using JAVA, you must include the main method as well which should test your other methods and print the outputs according to the tasks.
  3. If you are using PYTHON, make sure your code has the methods invoked and proper printing statements according to the tasks.
  4. Your program will take an arithmetic expression as a string input. For Example:

     

    • “1+2*(3/4)”

     

    • “1+2*[3*3+{4–5(6(7/8/9)+10)–11+(12*8)]+14”

     

    • “1+2*[3*3+{4–5(6(7/8/9)+10)}–11+(12*8)/{13+13}]+14”

I. [10 marks For each row in the table below, determine what would happen if you opened DrScheme and tried to evaluate the given code. If there is an error, brielly explain what is wrong (be more specific than saying "invalid Scheme expression"). If there is no error, give the value produced by DrScheme. The first two rows have been completed for you as examples. Answer Scheme Code (+ 12) (+ 1 2)) (7 + 12) Error.
