voidreverse(ExecutionPolicy&&policy, BidirIt first, BidirIt last); (2)(C++17 起) 1)反转[first,last)范围中的元素顺序。 表现如同将std::iter_swap应用到对于[0,std::distance(first, last)/2)中的每个整数i对应的一对迭代器first+i和(last-i)-1上。
ForwardIt reverse_copy(ExecutionPolicy&&policy, BidirIt first, BidirIt last, ForwardIt d_first); (2)(C++17 起) 1)给定NN为std::distance(first, last)。将范围[first,last)(源范围)中的元素复制到从d_first开始的包含NN个元素的新范围(目标范围),使得目标范围中元素以逆序排列。
