Use of Multi-Language (Coding): Delete Nodes > X Test

The program defines a Node class with val and next attributes, and a removeNodes function that takes the head of a linked list and an integer x as input, and returns the updated head after removing all nodes with values greater than x. The Main function takes the input string in the format "element1 element2 ... - x", creates a linked list, calls the removeNodes function, and prints out the updated linked list. The program also includes a printLinkedList function to print out the elements of a linked list.

Skills measured

Understanding linked lists is fundamental in computer science and programming. A linked list is a data structure consisting of nodes, where each node contains a data element and a reference (or pointer) to the next node in the sequence. Mastery of linked lists is essential for efficient memory management and dynamic data manipulation, particularly in scenarios where the size of the data is unknown or changes frequently. By learning about linked lists, individuals gain valuable insight into data organization, traversal, insertion, and deletion operations, enhancing their ability to design and implement efficient algorithms and data structures.
