ExamplesApproach to solve this problemStep 1 − Define a method that accepts the head of a linked list.Step 2 − If head == nil, create a new node and make it head and return it as the new head.Step 3 − When index == 0, then update the head.Step 4 − Iterate the given linked list from its head. Also, initialize preNode that will keep the store address of the previous node.Step 5 − If index i matches with the given index, then then delete that node.next, break the loop.Step 6 − Return, at the end of loop.Example Live Demopackage main ...
