priority_queue和queue以及stack一样,他们都是由底层容器适配出来的适配器,之不过priority_queue采用的适配容器不再是deque而是vector,选择vector的原因也非常简单,在调用向上或向下调整算法时,需要大量频繁的进行下标随机访问,这样的情境下,vector就可以完美展现出自己结构的绝对优势。 1.2 向下调整算法建堆 1. 在建堆时...
temp.next =newListNode(stack.pop().val); temp = temp.next; }returnres.next; } 06 第五种解法 此解法与第四种解法思路类似,只不过是将栈换成了数组,然后新建node节点,以数组最后一位元素作为节点值,然后开始循环处理每个新的节点。 publicListNodereverseList5(ListNode head){if(head ==null|| head.ne...
