Bracket Matching

Create a method in ruby called test_brackets that takes a string and determines if all brackets are correctly matching / nested (returns true or false). This is code could be used as part of a system to detect syntax errors in code.

It should check for the following: [ ],{ },( )

Usage Examples

test_brackets('abc(123)')
#returns true

test_brackets('abc(123')
#returns false -- missing closing bracket

test_brackets('a[bc(123)]')
#returns true

test_brackets('a[bc(12]3)')
#returns false -- improperly nested

test_brackets('a{b}{c(1[2]3)}')
#returns true

test_brackets('a{b}{c(1}[2]3)')
#returns false -- improperly nested

test_brackets('()')
#returns true

test_brackets('[]]')
#returns false - no opening bracket to correspond with last character

test_brackets('abc123yay')
#returns true -- no brackets = correctly matched
