# Test a String for '(),[],{}' well-formedness
|
|
|
|
## Goal
|
|
A string over the characters `()[]{}` is said to be well-formed, if the different types of brackets match __in the correct order__.
|
|
|
|
Write a program that outputs `true` or `false` depending on the well-formedness of the input.
|
|
|
|
### Example
|
|
|
|
| Input | Output |
|
|
|----------|--------|
|
|
| ([{}])() | true |
|
|
| ([)] | false |
|
|
|
|
### Constraints
|
|
Input strings consist only of characters `()[]{}`
|
