Linked List
In "Inbound Link Reversal", a singly linked sequence is represented as an array in input order.
Return the sequence in reversed order as if the linked list pointers were fully reversed.
Example 1
Input:
head = [20,21,22,23,24]Output:
[24,23,22,21,20]For input head = [20,21,22,23,24], reversing the node direction makes the values appear in reverse order, so the output is [24,23,22,21,20]. Therefore, return [24,23,22,21,20].
Example 2
Input:
head = [40,41]Output:
[41,40]For input head = [40,41], reversing the node direction makes the values appear in reverse order, so the output is [41,40]. Therefore, return [41,40].
Constraints
0 <= head.length <= 5000-5000 <= head[i] <= 5000
