The brand-new list should be made by splicing with each other the nodes of the initial two listings. "(Remedy )"You are offered an array of k linked-lists checklists, each linked-list is sorted in ascending order. Merge all the linked-lists right into one arranged linked-list and return it."(Service)"A linked listing is given such that each node contains an added random pointer which might aim to any node in the list or null.
