What is Loop in Linked List? In a standard singly linked list, the last node always points to NULL. If you traverse such a linked list, the traversal will end at the last node. That means you can not go anywhere from the last node. Here is an example of a standard linked list. Loop … Continue reading “Detect and Remove Loop in Linked List in C”
C Program to Sort Linked List without Allocating Extra Memory
We’ll first create a linked list which is not sorted, then we’ll re-arrange the list such that the list becomes sorted. Logic is simple, we’ll iterate the list for all nodes, in every iteration we’ll take the first node out of the original list and insert that node into a new list. At any point … Continue reading “C Program to Sort Linked List without Allocating Extra Memory”
C Program to Convert Binary Number to Decimal
Binary number system is 2-based which means at most two symbols, 0 (zero) and 1 (one), can be used to represent a binary number. Example of binary number is 110110011, sometimes binary numbers are written as 1101100112, where 2 is represented as base of the number system. Binary number system is the basis of all computer and digital systems. … Continue reading “C Program to Convert Binary Number to Decimal”
