https://www.geeksforgeeks.org/lower_bound-in-cpp/ 在有序数组中,找到大于或等于目标值的数据集合中值最小的位置。 Thelower_bound()method in C++ is used to return an iterator pointing to the first element in the range [first, last) which has a value not less than val. This means that t...
lower_bound upper_bound in cpp upper_bound Returns an iterator pointing to the first element in the range [first,last) which compares greater than val. Return value An iterator to the upper bound position for val in the range. If no element in the range compares greater than val, the fun...

map::upper_bound(key):返回map中第一个大于key的迭代器指针 所以,理解这两个函数请不要按照字面意义思考太复杂,因为仅仅是不小于(lower_bound)和大于(upper_bound)这么简单。 看两个msdn里的例子 // map_upper_bound.cpp // compile with: /EHsc ...

std::lower_bound() 是一个 STL 库函数,它属于算法头库,在一个范围内找到搜索元素的下界。下限是指范围内大于或等于搜索元素的最小元素。 假设范围是:[4, 5, 6, 9, 12] 并且搜索元素是6,那么下限是6本身。如果搜索元素为 7,则下限为 9 案例: ...
I am doing hackerrank questions and one requires the use of lower_bound, so i read it on the cpp.reference, and it says "Returns an iterator pointing to the first element in the range [first, last) that is not less than (i.e. greater or equal to) value, or last if no such elem...
