lower_bound() 函数返回一个迭代器,指向范围中第一个不小于指定值的元素,而 upper_bound() 函数返回一个迭代器,指向范围中第一个大于指定值的元素。"lower bound" 和 "upper bound" 这些术语在数学中通常用于描述某个限制范围内的值范围,这就是为什么在 C++ 中这些函数被命名为这样的原因。
但是，这并不完全正确，lower_bound和upper_bound都返回满足特定规则的序列的first元素，因此它们都不直接...

lower_bound给你第一个，upper_bound给你一个过去的结束。这是STL范围[first, last)的正常模式。
因此，如果有一个范围的值对于所使用的比较是“相等的”，lower_bound给你第一个，upper_bound给你一...

from above and therefore has no upper bound; it is sometimes said that its upper bound is equal to + ∞. The lower bound of setEis defined analogously to the upper bound as the greatest of the numbersB, which possess the property such that for anyxofEthe inequalityx ≥ Bis satisfied. ...
Upper Bound = None (or infinity) Please note that these bounds are valid under the typical definition of natural numbers where the set starts from 1. If your definition includes 0 as a natural number, then the lower bound would be 0. ...
Moreover, the optimal entangled strategy is very simple, involving observables defined by tensor products of the Pauli matrices.Additionally, we give the first upper bound on the maximal QC-gap in terms of the number of questions per player, showing that our construction is only quadratically ...
