二分查找方法//set//本题用的upper_bound(make_pair(a[pos]+d,INF))后面的INF一定要加,现根据前面查找,然后根据后面查找,均二分//本题用的lower_bound(make_pair(a[pos]+d+1,0))后面o也一定要加,现根据前面查找
lower_bound: 返回一个ForwardIterator,指向在有序序列范围内的可以插入指定值而不破坏容器顺序的第一个位置。重载函 数使用自定义比较操作。 upper_bound: 返回一个ForwardIterator,指向在有序序列范围内插入value而不破坏容器顺序的最后一个位置,该位置标志 一个大于value的值。重载函数使用自定义比较操作。 search: ...
不对啊,我那种方法其实修改一下也是正确的,用set维护一个pair<前缀,当前下标>,然后每次二分查找pair<那个值,上一次查找的下标>,这样找到的就是pair<那个值,那个下标后面的值>或者pair<大于那个值,下标无所谓>,我们在if判断一下是否是第一种,就可以了。
