    Why we cant take only ptr as a new node ...why we need to take 2 new nodes ?

      in the last part, we are just reallocating the head, such that the linked list is actually reversed. Follow the pointers and you will understand.

    thanks a lot ! This was easy to understand.I took a udemy course on dsa But they don't teach with diagrams like you do. Please if you any paid subscription let me know i would buy for sure. Also if possible can u suggest some good resources(books or courses) which are more diagram oriented rather than just running a code .

      Thank you so much for your feedback and motivation. Right now all my content is only on UA-cam and the website. Sure, if I add more subscription based course, you will know about it.

      What part are you facing a problem with?

  • @johncho9160
    @johncho9160 11 місяців тому +1

    why do you have to initialize the reversedList with Integer.MIN_VALUE? the value we assign does not matter since we are returning reversedList.next at the end anyway?

    • @nikoo28
      @nikoo28  11 місяців тому

      you are correct...it is just a dummy node. You can assign any value to it. It is just for utility.

  • @MaulikDodiaHollywoodMovieLover
    @MaulikDodiaHollywoodMovieLover 8 місяців тому

    currNode.next = preNode; ----> Is this statement only assign preNode's value to currNode's next node which is 8. and If this statement is assigning values then how ListNode nextNode = currNode.next; ---> this statement giving us next node. Confusing!
