You are given two sorted linked lists. You have to merge them to produce a combined sorted linked list. You need to return the head of the final linked list.
Note:
The given linked lists may or may not be null.
For example:
If the first list is: 1 -> 4 -> 5 -> NULL and the second list is: 2 -> 3 -> 5 -> NULL
The final list would be: 1 -> 2 -> 3 -> 4 -> 5 -> 5 -> NULL

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.
Problem approach
Did using stack approach. Compared the closing bracket in string with element in stack and pop the top from stack.
