questions raised: M (such as 1 billion int integer, where the number of n is repeated, read into memory, and delete the repeating integer. Problem Analysis: we would have thought about opening up an array of M int integers in computer memory, one bye to read an array of M int, then a one by one comparison value, and finally the deduplication of the data. This is, of course, feasible in dealing with small-scale data. We consider the case of big data: f

1097. Deduplication on a Linked List (25)Given a singly linked list L with integer keys, you is supposed to remove the nodes with duplicated absolute values of th e keys. That's, for each value K, only the first node of which the value or absolute value of its key equals K would be kept. At the mean time, all the removed nodes must is kept in a separate list. For example, given L being 21→-15→-15→-7→15, you must output 21→-15→-7, and the removed list-

Array_flip is a function that reverses the array key and value. It has a feature that if two values in the array are the same, the last key and value will be retained after the inversion.Value.
