How do you check if a linked list is a palindrome in C?

How do you check if a linked list is a palindrome in C?

To check whether a list is a palindrome, we traverse the list and check if any element from the starting half doesn’t match with any element from the ending half, then we set the variable flag to false and break the loop. In the last, if the flag is false, then the list is palindrome otherwise not.

Can we reverse a linked list in less than O N time?

No, we cannot reverse a linked list in O(n) time, because each pointer must be reversed or values must be interchanged to reverse a linked list. To do that we need to reach the last node which takes a pointer to reach last node which takes O(n) time. It can`t even be done by using recursive and iterative methods.

How to check if a linked list is palindrome?

1 Get the middle of the linked list. 2 Reverse the second half of the linked list. 3 Check if the first half and second half are identical. 4 Construct the original linked list by reversing the second half again and attaching it back to the first half

How to iterate over a palindrome list in Python?

Iterate over the list to count how many elements there are. Iterate a second time, and starting from the middle of the list, reverse the pointers in the list nodes so that they point to the previous node rather than the next. Remember the last node.

Is the data value of the singly linked list is only numbers?

A palindrome is nothing but a string or number which is same whether you read it from right to left or left to right. It is like the string and its mirror image both are same. Is the data value of the given Linked List is only numbers? (Ans: No, the data values can be anything.)
