Insertion Sort Algorithm in PYTHON

Insertion sort is based on the idea that one element from the input elements is consumed in each iteration to find its correct position i.e, the position to which it belongs in a sorted array. It iterates the input elements by growing the sorted array at each iteration. It compares the current element with the largest value in the sorted array.

Insertion is a simple way or simple algorithm to sort a list. It is much more efficient than bubble sort. But for larger list Insertion sort is not suggested. For that we will study about merge sort and quick sort algorithms. But in this this tutorial we will learn INSERTION SORT algorithm and data structure.


ALGORITHM

1.) First of all take a list. Now compare the second element of the list with left hand side elements of the list i.e. the first element. If second element id greator than swap.

2.) Now take third element, compare it with the left hand side elements i.e. first and second element and place the element accordingly the first and second element.

3.) Go on until the last element, and compare the left hand side elements and place accordingly. 

4.) Sorted list will be printed. So this was the simple algorithm.


DATA STRUCTURE in PYTHON





This was the the simple algorithm and data structure of the Insertion Sort. Hope you like this tutorial. Please share it with your friends. In the next tutorial, we will learn about SELECTION SORT algorithm and data structure.

First Python Programme

  If you are here, then I think you are a python enthusiast. On this website, we upload daily posts on new and basic programme for beginners.  So let’s start with the first code i.e. Hello World programme. So first of all you you should know how to give print command in python. To print we write print(“Hello World”). What’s inside the small brackets will be printed. So the programme is : print("Hello World") Hello World So, as we can see above, when we implemented the print command, the thing between the small bracket is printed. So let’s see some other examples In this example, we will store an integer value in a variable. And then print the integer will the help,of that variable. So let’s get started a = 3 print(a) 3 Another example Now we will store a string into a variable and then print the string with the help of that variable #if we put hastag in front of any line in python. Then there is no effect. #for storing the string in a variable, we have to enclose the whole s...

Doubly Linked List in PYTHON

  Here is the Python code for the Doubly Linked List :- #first of all creat a class node class Node :     def __init__ ( self , data ):         self . data = data         self . next = None         self . prev = None #now create a class of doubly linked list class DLL :     def __init__ ( self ):         self . head = None #function to insert the node at begining     def insertatbeg ( self , data ):         newnode = Node ( data )         newnode . prev = None         newnode . next = self . head         self . head = newnode #function to insert the node at the end     def insertatend ( self , data ):         newnode = Node ( data )         if self . head is None :             self . head ...

Queues in PYTHON

  The Python Code for Queue is here :- class Node: def __init__(self, data): self.data = data self.next = None class Queue: def __init__(self): self.front = self.rear = None def enqueue(self, data): newnode = Node(data) newnode.next = self.rear self.rear = newnode if self.front is None: self.front = newnode def dequeue(self): temp = self.rear while temp.next is not self.front: temp = temp.next self.front = temp temp.next = None def traverse(self): temp = self.rear while temp is not None: print(temp.data, end = " --> ") temp = temp.next print("None") new = Queue() new.enqueue(4) new.enqueue(1) new.enqueue(0) new.enqueue(2) new.traverse() new.dequeue() new.traverse() new.dequeue() new.traverse() 2 --> 0 --> 1 --> 4 --> None 2 --> 0 --> 1 --> None 2 ...
