When reversed, the new number becomes 2324321 which is not the same as the original number. Reading the given input number using input () or the raw_input (). We shall keep posting many more articles on implementing data structures and algorithms using Python. Content Policy | The process of doing the reverse of the number is easy and checks it for the readable, reducing code to operate. The next step is that use while loop and last digit of numbers us obtained by modulus operator. Print(“Is the number palindrome? They are also called Symmetrical Alphabets. print(“No”) filter_none. It performs reverse on the input string but does not change the given string. A number is said to be palindrome if it is equal to its reverse. Instead of reversing the entire linked list, and storing it in a temporary location, we reverse the first half of the linked list, and check if the first half and second half match after reversal. Then check value entered is the integer or not. The logic for checking if a linked list is a palindrome or not is the modified version of the one we implemented on strings and arrays. @Reinderien and @vlovero have already told whatever could be done but maybe you would also like the reversed function. About US | Pavitra.
