使用递归的策略，十分方便！
class Solution {
public:
ListNode* Merge(ListNode* pHead1, ListNode* pHead2) {
if (!pHead1 && !pHead2) return nullptr;
if (!pHead1) return pHead2;
if (!pHead2) return pHead1;
if (pHead1->val <= pHead2->val) {
auto tmp = pHead1->next;
pHead1->next = Merge(tmp, pHead2);
return pHead1;
} else {
auto tmp = pHead2->next;
pHead2->next = Merge(tmp, pHead1);
return pHead2;
}
}
};
