NettetThe std::all_of () function is a STL Algorithm in C++. It can be used to check if all the elements of a sequence satisfies a condition or not. The sequence can be a vector, array, list or any other sequential container. We need to include the header file to use the std::all_of () function. Nettet9. mar. 2024 · Approach: Create a map that will store the visited node in the linked list. Traverse the linked list and do the following: Check whether the current node is present on the map or not. If the current node is not present in the map then, insert the current node into the map. If the Node is present in the map, the loop in a linked list is detected.
