Problem statement

You're given a string 'S' consisting of "{", "}", "(", ")", "[" and "]" .

Return true if the given string 'S' is balanced, else return false.

For example:

'S' = "{}()".

There is always an opening brace before a closing brace i.e. '{' before '}', '(' before ').
So the 'S' is Balanced.

Detailed explanation ( Input/output format, Notes, Images )

Input Format:

The first and only input line contains a string 'S'.

Output format :

The only line of output contains 'Balanced' or 'Not Balanced'.

Note:

You are not required to print anything explicitly. It has already been taken care of. Just implement the given function.

[()]{}{[()()]()}

Balanced

There is always an opening brace before a closing brace i.e. '{' before '}', '(' before '), '[' before ']'.
So the 'S' is Balanced.

[[}[

Not Balanced

1 <= 'N' <= 10^5

Where 'N' is the length of the input string 'S'.
