Brackets Task

Issue

At the input there is a line containing only brackets from the set {}()[]. It is necessary to determine whether it is balanced or not.

A balanced line is a string in which three conditions are fulfilled:

• for each opening bracket there is a corresponding closing;
• the corresponding closing bracket must be after the opening bracket;
• between the two corresponding brackets there are no other brackets without the correspondences between these brackets.

That is, [([]{[]})] is balanced, but {[}], [{)] and ]{}[ - are not.
