Hi i am taking a java class and i am stuck on this question.

For IntArrayBag class, implement a new method called equals with a boolean return value and one parameter. The parameter, called b, is another IntArrayBag. The method returns true if b and the bag that activates the method have exactly the same every element. Otherwise, the method returns false. Notice that the locations of the elements in the data array are not necessarily the same. It is only the number of occurrences of each element that must be the same. The worst-case time for the method should be O(mn), where m is the size of the bag that activates the method and n is the size of b. Test your equals method. You can copy the implementation of IntArrayBag and add your equals method to it.
