An array that is first 7-sorted, then 5-sorted becomes _________ Correct Answer both 7-ordered and 5-ordered

An array that is 7-sorted, becomes 7-ordered. And an array that is 5-sorted, becomes 5-ordered. If k-ordered array is h-sorted, it remains k-ordered. Thus, an array that is first 7-sorted, then 5-sorted becomes both 7-ordered and 5-ordered.
