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...

因此,在处理算法时,最好将关联容器上的迭代器视为支持自减运算的输入迭代器,而不是完整的双向迭代器。 最后需要注意的是,stack、queue、priority_queue 都不支持任一种迭代器,它们都是容器适配器类型,stack是用vector/deque/list对象创建了一个先进后出容器,queue是用deque或list对象创建了一个先进先出容器,priorit...
