Delete Nodes Greater Than X

The node values of a singly linked list are given in their original order. Delete every node whose value is greater than x and output the remaining nodes without changing their order; nodes equal to x are kept.

输入格式

The input is n x, followed by n node values. The original bounds are kept: 1≤n≤100000, 1≤x≤100000, and node values in 1..100000.

输出格式

Output the remaining node values in their original order, separated by spaces; if all nodes are deleted, output an empty line. Do not output the number of nodes.
