NettetThen the T test cases follow. The first and only line of each test case contains the elements of the linked list separated by a single space and terminated by -1. Hence, -1 would never be a list element. Output Format : For each test case, print “True” if the given linked list is a palindrome, else print “False”. Note: NettetThen traverse the linked list again, and for each node, pop the top element from the stack and compare it with the node’s data. If a mismatch happens for any node, we can say that the linked list is not a palindrome. The algorithm can be implemented as follows in C++, Java, and Python:
