Are the brackets balanced?

A code editor underlines a line when its brackets don't match. Brackets are (), [] and {}: every opening bracket must be closed by the same kind, and pairs must nest, so ([)] is wrong. All other characters are ignored.

Functionbalanced(text)

ReturnsTrue if every bracket is closed by the right kind in the right order, otherwise False

Examples

callbalanced('[1, (2, 3)]')returnsTrue

callbalanced('([)]')returnsFalse

callbalanced('{"a": [1, 2]}')returnsTrue
