C++ Input and Output: Understanding cin, cout, cerr and clog with Examples

In C++, input and output (I/O) operations are performed using the standard input/output library, which is defined in the <iostream> header file. The basic I/O operations in C++ are performed using the following four standard streams: Here’s an example of a simple program that uses cin and cout to read an integer from the keyboard

Leet Code :Linked List Cycle II Java || Python || C++ solution

leetcode question solution

Given the head of a linked list, return the node where the cycle begins. If there is no cycle, return null. There is a cycle in a linked list if there is some node in the list that can be reached again by continuously following the next pointer. Internally, pos is used to denote the index of the node that tail’s next pointer is connected
