Given the head
of a singly linked list and two integers left
and right
where left <= right
, reverse the nodes of the list from position left
to position right
, and return the reversed list.
Example 1:
Input: head = [1,2,3,4,5], left = 2, right = 4 Output: [1,4,3,2,5]
Example 2:
Input: head = [5], left = 1, right = 1 Output: [5]
Constraints:
- The number of nodes in the list is
n
. 1 <= n <= 500
-500 <= Node.val <= 500
1 <= left <= right <= n
