 <pre>
 <strong>输入：</strong>intersectVal = 0, listA = [2,6,4], listB = [1,5], skipA = 3, skipB = 2
-<strong>输出：</strong>null
+<strong>输出：</strong>No intersection
 <strong>解释：</strong>从各自的表头开始算起，链表 A 为 [2,6,4]，链表 B 为 [1,5]。
 由于这两个链表不相交，所以 intersectVal 必须为 0，而 skipA 和 skipB 可以是任意值。
 这两个链表不相交，因此返回 null 。
