# 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 `()[]{}`
