    1290 - Convert Binary Number in a Linked List to Integer.

    Easy

    Given head which is a reference node to a singly-linked list. The value of each node in the linked list is either 0 or 1. The linked list holds the binary representation of a number.

    Return the decimal value of the number in the linked list.

    Example 1:

    Input: head = 1,0,1

    Output: 5

    Explanation: (101) in base 2 = (5) in base 10

    Example 2:

    Input: head = 0

    Output: 0

    Constraints:

    • The Linked List is not empty.

    • Number of nodes will not exceed 30.

    • Each node's value is either 0 or 1.
