And for the need to move to the last batch of elements, it is necessary to move the relatively small number of those elements, so as to ensure that they as far as possible forward.Import Java.io.ioexception;import java.util.arrays;import Java.util.comparator;import Java.util.LinkedList;import Java.util.scanner;impor
