Solution: Remove Nth Node from End of List
Understand how to remove the nth node from the end of a singly linked list using the two-pointer approach. Learn to advance one pointer n steps ahead, then move both until the end, enabling single-pass removal while maintaining O(N) time complexity and O(1) space complexity.
Statement
Given the head of a singly linked list and an integer n, remove the nth node from the end of the list and return the head of the modified list.
Constraints:
The number of nodes in the list is
