These are a function to generate a random string of N brackets of each type,
and a function to check whether a given string of brackets is balanced.
<lang APL>gen ← (⊂+?+)⍨ ⌷ ('[]'/⍨⊢)
bal ← ((|≡⊢)+\ ∧ 0=+/)(+⌿1 ¯1×[1]'[]'∘.=⊢)</lang>
Sample run for 0..N..10:
<lang APL> ↑{br←gen ⍵ ⋄ br,': ',(1+bal br)⊃'Bad' 'Good'}¨0,⍳10
: Good
[]: Good
][][: Bad
[][[]]: Good
[]]][[][: Bad
][][[[[]]]: Bad
][][][][][[]: Bad
][[[][[][]][]]: Bad
[[][[]]][[[[]]]]: Good
[[[]][[[[][]][]]]]: Good
]][][][][[][][]][[[]: Bad</lang>
