C++ STL set::upper_bound() function: Here, we are going to learn about the upper_bound() function of set in C++ STL (Standard Template Library).
示例1:找到multiset中第一个大于指定值的元素 #include<iostream>#include<set>intmain(){std::multiset<int>ms={3,4,5,5,5,7,7,8};intval=6;autoit=ms.upper_bound(val);if(it!=ms.end()){std::cout<<"The first element greater than "<<val<<" is "<<*it<<std::endl;}else{std::cout...

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 ...

Returns: The furthermost iterator i in the range [first, last] such that for every iterator j in the range [first, i) the following corresponding conditions hold: !(value < *j) or comp(value, *j) == false. 分析 为何如此设计? 这是有原因的。lower_bound 和upper_bound 的比较函数都只能...
cpp 原创 woxinpengpai 2023-06-14 10:22:33 96阅读 lower_bound() 与upper_bound() 1. lower_bound() lower_bound()是泛型算法,在使用时,需要先将序列进行排序; 作用: 函数lower_bound()在first和last中的前闭后开区间进行二分查找,返回大于或等于val的第一个元素位置。如果所有元素都小于val,则返回las...
返回類型:返回類型是在範圍內找到的上限的迭代器。 如果您有用戶定義的數據類型,這會很有幫助。 注:本文由純淨天空篩選整理自std::upper_bound() function with example in C++ STL。非經特殊聲明,原始代碼版權歸原作者所有,本譯文未經允許或授權,請勿轉載或複製。
