Delete kth element from end of Linked List

In this post, we will discuss a method to delete the kth element from the end of the linked list. In order to delete the required node, we first need to find the kth element from the end of the linked list and then we can delete that element, so in one of the previous posts we have discussed a method to find kth element from the end of the linked list and In another post we have seen a method to delete node from linked list with the only pointer to that node, So combining the 2 methods we can delete the kth element from the end of the linked list.

Have a look at the below posts for an explanation of the methods used in this post

  1. Finding kth element from the end of the Linked list 
  2. Deleting element from the Linked List with only pointer to that node 
Algorithm
  1. Initialize 2 pointers first and second to head node 
  2. Move node first to the kth node from the start 
  3. Move both first and second node through the list till the first node reaches the last node 
  4. At this point, the second node points to the kth node from the end 
  5. Delete the second node using delete method.


We use the same algorithm that we used in our earlier post to delete the node. But this time we will pass the pointer that points to the kth element from the end to the method.

Let look at the code.

Infix to Prefix conversion using Stack

This post is about conversion of Infix expression to Prefix conversion. For this conversion we take help of stack data structure, we need to push and pop the operators in and out of the stack.

Infix expressions are the expressions that we normally use,eg. 5+6-7; a+b*c etc. Prefix expressions are the expressions in which the 2 operands are preceded by the operator eg. -+567 , +a*bc etc.

This method is very similar to the method that we used to convert Infix to Postfix but the only difference is that here we need to reverse the input string before conversion and then reverse the final output string before displaying it.

NOTE: This changes one thing that is instead of encountering the opening bracket we now first encounter the closing bracket and we make changes accordingly in our code.

So, to convert an infix expression to a prefix expression we follow the below steps
(we have 2 string, 1st is the input infix expression string 2nd is the output string which is empty initially)


We first revers…

Hashing with Quadratic Probing

Hashing is a technique used for storing , searching and removing elements in almost constant time. Hashing is done with help of a hash function that generates index for a given input, then this index can be used to search the elements, store an element, or remove that element from that index.

A hash function is a function that is used to map the data elements to their position in the data structure used. For example if we use an array to store the integer elements then the hash function will generate position for each element so that searching, storing and removing operation on the array can be done in constant time that is independent of the number of elements in the array. For better look at the example below.



now we face a problem if for 2 numbers same position is generated example consider elements 1 and 14

1 % 13 = 1

14 % 13 = 1

so when we get 1 we store it at the first position, but when we get 14 we see that the position 1 is already taken, this is a case of collision.

Inorder…
