Given the head node of the singly linked list and an integer ‘k’, , find the value at the kth node from the end of the linked list.

For example:

For the above-linked list, if k=2, then the value at the kth i.e second node from the end is ‘12’.

Note :

1.You don’t need to take any input. It has already been taken care of. Just implement the given function and return a pointer pointing to the k-th element from the last of the linked list.
2.It is guaranteed that k<=size of the linked list.

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.
