vector删除元素之pop_back(),erase(),remove() 向量容器vector的成员函数pop_back()可以删除最后一个元素. 而函数erase()可以删除由一个iterator指出的元素,也可以删除一个指定范围的元素。 还可以采用通用算法remove()来删除vector容器中的元素. 不同的是:采用remove一般情况下不会改变容器的大小,而pop_back()与...
Solution { public: int removeDuplicates(vector& nums) { int num = nums.size();//计算删除重复元素数组中的元素个数...]; } cout << endl; } int main() { test(); system("pause"); return 0; } 双指针法首先注意数组是有序的...,那么重复的元素一定会相邻。...要求删除重复元素,实际上就...
复制 add_subdirectory(source_dir [binary_dir] [EXCLUDE_FROM_ALL]) 如前所述,这将为我们的构建添加一个源目录。可选地,我们可以提供一个路径,其中将生成文件(binary_dir)。EXCLUDE_FROM_ALL关键字将禁用子目录中定义的目标的默认构建(我们将在下一章讨论目标)。这对于分离不需要核心功能的项目的部分(例如示例...

How I wish, but given that import <vector>; is a thing, there's no real way to avoid it in practice. Any C++ which is modules XOR headers is doomed because the valley between them is far too vast for many projects to migrate over. And if Qt and the STL can't move, which side...
