## brackets |
||||
|
||||
### Instructions |
||||
|
||||
Write a program that takes an undefined number of strings in arguments. For each |
||||
argument, the program prints on the standard output "OK" followed by a newline |
||||
if the expression is correctly bracketed, otherwise it prints "Error" followed by |
||||
a newline. |
||||
|
||||
Symbols considered as 'brackets' are brackets '(' and ')', square brackets '[' |
||||
and ']'and braces '{' and '}'. Every other symbols are simply ignored. |
||||
|
||||
An opening bracket must always be closed by the good closing bracket in the |
||||
correct order. A string which not contains any bracket is considered as a |
||||
correctly bracketed string. |
||||
|
||||
If there is no arguments, the program must print only a newline. |
||||
|
||||
And its output : |
||||
|
||||
```console |
||||
student@ubuntu:~/student/test$ go build |
||||
student@ubuntu:~/student/test$ ./test '(johndoe)' | cat -e |
||||
OK$ |
||||
student@ubuntu:~/student/test$ ./test '([)]' | cat -e |
||||
Error$ |
||||
student@ubuntu:~/student/test$ ./test '' '{[(0 + 0)(1 + 1)](3*(-1)){()}}' | cat -e |
||||
OK$ |
||||
OK$ |
||||
student@ubuntu:~/student/test$ ./test | cat -e |
||||
$ |
||||
student@ubuntu:~/student/test$ |
||||
``` |
