std::lower_bound()将迭代器返回到元素本身 当搜索元素不存在时: 如果所有元素都大于搜索元素: lower_bound()返回一个迭代器到范围的开始。 如果所有元素都低于搜索元素: lower_bound()返回到范围末尾的迭代器(不存在下限)。 否则, lower_bound()返回一个迭代器到范围的搜索元素(比搜索元素大的最接近的元素)的...
lower_bound's return value is the iterator for the first element in the container that isgreater than or equal tovalue, or, when the comparison operator is used, the first element that does not satisfy the comparison function. Formally, the algorithm returns an iteratoriin the range[first, ...
C++ STL set::lower_bound() function: Here, we are going to learn about the lower_bound() function of set in C++ STL (Standard Template Library).
std::lower_bound()is an STL library function, which comes under the algorithm header library and finds the lower bound of the searching element in a range. Lower bound means the least element in the range which is greater or equal to the searching element. ...
Function Details const_iterator lower_bound(const key_type &x) const Find the greatest key less than or equal to x. Parameters x The target key to find. Return Value The valid const iterator sitting on the key, or an invalid one. See Also http://www.cplusplus.com/reference...

If you look closely on documentation on cppreference you will see that the function std::lower_bound works in linear time if container iterators are not RandomAccess. Set iterators are Bidirectional. std::find works always in linear time. So set.find and set.lower_bound are coded specifically...
