作用：倒置或調換區間元素的位置
聲明：
#include?<algorithm>?? template?<class?biDirectionalItr>?? void?reverse(biDirectionalItr?first,?biDirectionalItr?last);?? ?? template?<class?biDirectionalItr,?class?outputItr>?? outputItr?reverse_copy(biDirectionalItr?first,?biDirectionalItr?last,outputItr?destFirst);?? ?? template?<class?forwardItr>?? void?rotate(forwardItr?first,?forwardItr?newFirst,?forwardItr?last);?? ?? template?<class?forwardItr,?class?outputItr>?? outputItr?rotate_copy(forwardItr?first,?forwardItr?middle,?forwardItr?middle,last,outputItr?destFirst);??
示例代碼：

運行結果：
intList
1 3 5 7 9 0 2 4 6 8
intList
8 6 4 2 0 9 7 5 3 1
resultList:
1 3 5 7 9 0 2 4 6 8
intList before ratete
8 6 4 2 0 9 7 5 3 1
intList after ratete
4 2 0 9 7 5 3 1 8 6
