iterator insert ( iterator position, const T& x );此函数的返回类型是指向插入元素的迭代器。我的问题是,考虑到这种返回类型,最有效的方法是什么(这是我正在运行的一个更大程序的一部分,速度是最重要的,所以我正在寻找一种计算效率最高的插入方式)。是下面的事吗?//Code 1vector<in 浏览3提问于201...

vector删除重复元素 主要思路为,先排序,再唯一,然后删除最后面的那段重复代码。举例:有这样一个vector int a[10] = {1,3,6,4,7,2,3,4,8,9}; // 1,2,3,3,4,4,6,7,8,9 vector<int> ivec(a, a+10);①首先将vector排序 sort( vecSrc.begin(), vecSrc.end() ); // 1,2,3,...
