Linked Checklist Palindrome Drawback Algorithm and Resolution rationalization 

As a result of these
variables are of kind node, they’ve entry to the occasion variables
declared in school “Node”, so values had been being assigned to them. Examine
strains 9 to 12.

Line 13 referred to as the tactic “isPalindrome” and
assigned it to a boolean variable situation. So if the situation is true
in line 15, it prints out “Linked listing is a palindrome” else, it does
in any other case

Line 20 is the implementation of the tactic
“isPalindrome” which takes in a parameter “head” of kind Node, In Line 24
the parameter was assigned to variable subsequent of kind node. Then one other
boolean variable examine, in line 25.

In line 26, A stack was created. So, whereas the following ingredient shouldn’t be null, the stack
pushes in information and afterward, there was a re-assignment for the variable
“subsequent”. One other iteration once more, whereas the pinnacle shouldn’t be null the stack pops
out ingredient and shops it within the variable i. 

In
Line 47 it returned the boolean examine.

From line 51 is the Node
class with occasion variables, int information, and Node ptr respectively.
Adopted by the constructor. It’s not obligatory you might have the node class
the identical class because it was finished right here. You possibly can at all times have it in a separate
file, simply that it needs to be in the identical bundle so you may import from
that very same bundle.

Output:
The linked listing is a palindrome.

That is all about find out how to examine if a given linked listing is a palindrome in Java or not. That is an attention-grabbing coding drawback, not only for interviews but additionally
to be taught linked listing information construction because it provides you a chance to
traverse a linked listing. You additionally find out how you should use stack to carry out
the Final In First Out form of operation which is vital to reverse a linked
listing or reverse some other information construction.
