g++ -std=c++11 test.cpp
find
```
template <class InputIterator, class T>InputIterator find (InputIterator first, InputIterator last, const T& val);
```
Returns an iterator to the first element in the range [first,last) that compares equal to val. If no such element is found, the function returns last.

copy

template <class InputIterator, class OutputIterator>OutputIterator copy (InputIterator first, InputIterator last, OutputIterator result);
Copies the elements in the range [first,last) into the range beginning at result.

copy_backward
```
template <class BidirectionalIterator1, class BidirectionalIterator2>BidirectionalIterator2 copy_backward (BidirectionalIterator1 first,                                    BidirectionalIterator1 last,                                    BidirectionalIterator2 result);
```
Bidirectional iterators to the initial and final positions in a sequence to be copied. The range used is [first,last), which contains all the elements between first and last, including the element pointed by first but not the element pointed by last.
从result指针的前一位开始，result指针前一位用last指针的前一位代替，result指针前2位用last指针的前2位代替.
