取而代之的是,我会简单地说明count和find算法都用相等来搜索,而binary_search、lower_bound、upper_bound和equal_range则用等价。 要测试在有序区间中是否存在一个值,使用binary_search。不像标准C库中的(因此也是标准C++库中的)bsearch,binary_search只返回一个bool:这个值是否找到了。binary_search回答这个问题:“...
Section II binary search in STL 如果在C++ STL容器中包含了有序的序列,STL提供了四个函数进行搜索,他们是利用二分查找实现的(Binary search). 其中: 假定相同值的元素可能有多个 lower_bound 返回第一个符合条件的元素位置 upper_bound 返回最后一个符合条件的元素位置 equal_range 返回所有等于指定值的头/尾元...

We discuss results from very long baseline interferometry (VLBI) observations of two Seyfert galaxies with double peaked emission lines in their SDSS optical spectra. Such AGN are potential candidates for the presence of binary black holes, which can be resolved on parsec-scales with VLBI. Our ob...

Given the head of a singly linked list where elements are sorted in ascending order, convert it to a height balanced BST. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of every node never differ by more than 1. ...
