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
