Construct and Print a Singly Linked List Problem Statement Given an array of integers, your task is to construct a singly linked list from these integers. After constructing the linked list, you should traverse it from the head to the tail and print the data stored in each node, separated by spaces. A singly linked list is a linear data structure where each element (called a node) points to the next node in the sequence. Unlike arrays, linked lists are dynamic in size and elements are not stored in contiguous memory locations. Input Specification The input will consist of a single line containing space separated integers representing the elements of the array. Output Specification Print the data of each node in the constructed linked list, from head to tail, separated by spaces. A newline character should follow the last printed element. Constraints The number of elements in the array will be between 1 and 10^5. Each integer in the array will be between 10^9 and 10^9.
