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.
