Get nth node in a linked list
WebJul 16, 2024 · The most efficient way of getting the nth node of a linked list is to have 2 pointers(p1 and p2). Initialize both the pointers to point to the head of the linked list initially; Move one of the pointers n nodes through the linked list; Now the distance between p1 and p2 is equal to n. Now, move both p1 and p2 until p1 reaches the end of the ... WebNov 4, 2024 · current.next points to the successive node – the nd node of the linked list.

WebMar 26, 2009 · Algorithm: 1. Initialize count = 0 2. Loop through the link list a. if the count is equal to the passed index then return the current node b. Increment count c. change current to point to next of the current. WebThe formula is: N th node from the end is the (s - n + 1)th node from the beginning, where is the total number of nodes present in the linked list. Thus, the 2 nd node from the end is the (6 - 2 + 1) = 5 th node from the beginning (6 is the size of the linked list mentioned in example 1). Thus, the approach is simple.
