类及方法的说明：

类：ElementCheck

CheckSameElement1(Vector<String> test)

Vector<String> test:目标数组

将目标数组中重复的元素的序号以Vector<Integer>类型返还，排序方式为重复优先

CheckSameElement2(Vector<String> test)

Vector<String> test:目标数组

将目标数组中重复的元素的序号以Vector<Integer>类型返还，排序方式为序号排列优先

CheckDifferentElement(Vector<String> test)

Vector<String> test:目标数组

将目标数组中不重复的元素的序号以Vector<Integer>类型返还
