int remove(E value) Searches for value and remove the item (that is equal to the value) of the first occurrence and return the item's index, or return -1 if cannot find an item that is equal to the value in the ArrayList. Hint: you can use two methods in the KWArrayList class to complete the removing and index returning operations described in the remove(E value) method.

public int remove(E value) {

return -1;

}
