WebOct 17, 2024 · Approach: Append Node with value zero at the starting of the linked list. Traverse the given linked list.; During traversal store the sum of the node value till that node with the reference of the current node in an unordered_map.; If there is Node with value (sum – K) present in the unordered_map then delete all the nodes from the node … WebInput: head = [1,2,3,3,4,4,5] Output: [1,2,5] Explanation. The idea here is to traverse our linked list and use two pointers: slow is for node just before duplications begins; fast is for the last node of the duplication group.; Now, we traverse nodes and do the following steps:
