ForwardIt reverse_copy(ExecutionPolicy&&policy, BidirIt first, BidirIt last, ForwardIt d_first); (2)(C++17 起) 1)复制来自范围[first, last)的元素到始于d_first的新范围,使得新范围中元素以逆序排列。 表现如同通过对于每个非负的i < (last - first)执行

dstVec每次都要resize,相当于全拷贝了一次了,在做copy就没意义了,reverse也不能直接设置size,有没有办法去掉这个赋值,比如直接new char[]这种方式,不会默认填充值 std::vector srcVec(300 * 1024 * 1024, 'a'); std::vector<char> dstVec; dstVec.resize(srcVec.size()); std::copy(std::execution::...
