+'''Task''':
+* Generate a string with <math>\mathrm{N}</math> opening brackets (“<code>[</code>”) and <math>\mathrm{N}</math> closing brackets (“<code>]</code>”), in some arbitrary order.
+* Determine whether the generated string is ''balanced''; that is, whether it consists entirely of pairs of opening/closing brackets (in that order), none of which mis-nest.

+'''Examples''':
+
+    (empty)   OK
+    []        OK   ][        NOT OK
+    [][]      OK   ][][      NOT OK
