Remove Nodes from Linked List In K-Group | c++ programe
Question-
Given the head of a linked list, reverse the nodes of the list k at a time, and return the modified list.
k is a positive integer and is less than or equal to the length of the linked list. If the number of nodes is not a multiple of k then left-out nodes, in the end, should remain as it is.
You may not alter the values in the list's nodes, only nodes themselves may be changed.
Approach-
Step 1- Reverse the first K-group using the recursive function ' reverse '
Step 2- Find the length of the remaining list ' getLength' function
Step 3- Call recursive function for reverse remaining parts
