Implement it on LeetCode. There's also a recursive approach: text function reverseList(head): if head == null or head.next == null: return head newHead = reverseList(head.next) head.next.next = head head.next = null return newHead The iterative approach is space. The recursive approach uses call stack space. Know both.
