Linked List Binary to Decimal

Create or traverse a singly linked list whose node values are binary digits and print the corresponding base-10 decimal value. Requirements Input line 1 is list_size, the number of nodes N. Input line 2 contains N space-separated integers, each 0 or 1, representing node data in list order. Build or traverse the linked list and convert the binary representation to a decimal integer. Constraint shown: 1 <= N <= 64. Print the decimal form of the binary input. Examples Input: 7 0 0 1 1 0 1 0 Output: 26 Explanation: the list represents binary 0011010, which is decimal 26. Notes The candidate who shared this prompt had one hidden linked-list test case fail, so handle leading zeros and the full N <= 64 range carefully.
