WebSep 23, 2024 · If we notice carefully, the first node of the loop is the first element that will appear twice while traversing the linked list with a loop. 1) We will first create a set, which will store the addresses of the nodes. 2) Now, we will traverse the given linked list. For every node, we will check if that node is present in the set or not. biochemical sedimentary rocks are made from
