编写顺序查找的方法public static int[] ordinalSearch(int data[],int key)，要求该方法返回一个数组（如果key存在，数组中各元素的值分别为关键字key在原数组data中的下标；如果key不存在，则返回一个长度为1的数组，数组元素为-1）。-Write a sequential search method public static int [] ordinalSearch (int data [], int key) This method returns an array (if the key exists, the value of each element in the array subscr ipt in the original array data for the keyword key　 if the key does not exist, it returns a length for an array of elements to-1).
