We are given a linked list with head as the first node. Let's number the nodes in the list: node_1, node_2, node_3, ... etc.
Each node may have a next larger value: for node_i, next_larger(node_i) is the node_j.val such that j > i, node_j.val > node_i.val, and j is the smallest possible choice. If such a j does not exist, the next larger value is 0.
Return an array of integers answer, where answer[i] = next_larger(node_{i+1}).
Note that in the example inputs (not outputs) below, arrays such as [2,1,5] represent the serialization of a linked list with a head node value of 2, second node value of 1, and third node value of 5.
Example 1:
Input: [2,1,5] Output: [5,5,0]
Example 2:
Input: [2,7,4,3,5] Output: [7,0,5,5,0]
Example 3:
Input: [1,7,5,1,9,2,5,1] Output: [7,9,9,9,0,5,0,0]
Note:
<li><code><span>1 <= node.val <= 10^9</span></code><span> for each node in the linked list.</span></li>
<li>The given list has length in the range <code>[0, 10000]</code>.</li>
