要实现类似std::remove的其他功能,可以根据需要自定义一个函数或者使用现有的STL算法进行组合。以下是一些例子:
template <typename ForwardIt, typename UnaryPredicate>
ForwardIt custom_remove_if(ForwardIt first, ForwardIt last, UnaryPredicate pred) {
ForwardIt result = first;
for (ForwardIt it = first; it != last; ++it) {
if (!pred(*it)) {
*result++ = std::move(*it);
}
}
return result;
}
template <typename ForwardIt>
ForwardIt move_duplicate_elements_to_end(ForwardIt first, ForwardIt last) {
first = std::remove(first, last, std::remove(first, last, std::end(last)));
return first;
}
template <typename ForwardIt, typename T>
void custom_replace(ForwardIt first, ForwardIt last, const T& old_value, const T& new_value) {
std::replace(first, last, old_value, new_value);
}
这些例子只是简单的示例,实际实现时可以根据具体需求进行更复杂的逻辑设计和优化。
