LeetCode Problem - 206
class Solution {
// Method to reverse a singly linked list
public ListNode reverseList(ListNode head) {
// Initializing variables to keep track of previous and current nodes
ListNode prev = null;
ListNode current = head;
// Iterating through the list
while(current != null){
// Storing the next node temporarily
ListNode temp = current.next;
// Reversing the link of the current node
current.next = prev;
// Moving to the next node
prev = current;
current = temp;
}
// Returning the new head of the reversed list
return prev;
}
}
