When you try to swap two nodes, you end up removing one instead. points to last node*/ temp2 = temp1->next /*temp2 is now a null pointer*/. Two pointers is really an easy and effective technique which is typically used for having N integers, find if there exists any pair of elements (A[i], A[j]) such that.
Given a linked list and two keys in it, swap nodes for two given keys. Nodes should be swapped Following are C and Java implementations of this approach. Write a C program to create a linked list and accept two node position Step by step descriptive logic to swap two nodes in a singly linked list.
Given a linked list and two keys in it, swap nodes for two given keys. .. Optimizations: The above code can be optimized to search x and y in single traversal. Say we have: Node1 -> Node2 -> Node3 -> Node4 -> Node5. To swap two nodes , you need to swap the next values of the ones before each of them, and also.
