Time complexity of insertat tail is O(n) where n is the number of nodes in linked list.Since there is a loop from head to end, the function does O(n) work. This method can also be optimized to work in O(1) by keeping an extra pointer to tail of linked list.. Hope you guys understand the simple solution of inserting a node at tail in linked list in java It would look something like: Store the 0th element of the array in a temporary variable. Shift all the elements one by one one position to the left. Put the 0th element stored in the temporary variable at the last position in the array. This completes 1 rotation of the array.
