Map lower bound

Web01. jan 2024. · For the considered model, the emergent interface excitations map to an integrable chain of fermionic particles. We discuss how this integrability is broken by geometric features of the bubbles and by corrections in inverse powers of the ferromagnetic coupling, and provide a lower bound to the timescale after which the bubble is ultimately ... Web有啊，就是 std::upper_bound。upper_bound返回的是第一个大于 value 的元素的迭代器，那么只需要将这个迭代器 -1 就能够得到最后一个小于等于 value 的元素的迭代器。当然你需要判断一下返回值是否等于begin，如果等于的话那就说明没有小于等于 value 的元素。

WebA similar member function, upper_bound, has the same behavior as lower_bound, except in the case that the set contains an element equivalent to val: In this case lower_bound returns an iterator pointing to that element, whereas upper_bound returns an iterator pointing to the next element. Parameters val Value to compare. WebThe lower bound of the element with a key of 2 in the map m1 is: 20. The upper bound of the element with a key of 2 in the map m1 is: 30. A direct call of upper_bound ( 2 ) gives 30, matching the 2nd element of the pair returned by equal_range ( 2 ). The map m1 doesn't have an element with a key less than 40.

Weblower_bound (key) 参数 说明 返回一个指向当前 map 容器中第一个大于或等于 key 的键值对的双向迭代器。 如果 map 容器用 const 限定，则该方法返回的是 const 类型的双向迭代器。 案例 使用lower_bound查找元素 使用 lower_bound 查找 map 中的元素 Web有时候比起手写二分，lowerbound与upper_bound函数方便的多。 当容器中的元素按照递增的顺序存储时，lower_bound函数返回容器中第一个大于等于目标值的位置，upper_bound函数返回容器中第一个大于目标值的位置。若容器中的元素都比目标值小则返回最后一个元素的下一个位置。
