1. Insertion Sort

Image
  Input A sequence of unordered number ( a1,a2,a3 .... an) Output a1 <= a2 <= a3 <= a4 <= .... <= an We start with insertion sort, which is an efficient algorithm for sorting a small number of elements . Insertion sort works the way many people sort a hand of playing cards. We start with an empty left hand and the cards face down on the table. We then remove one card at a time from the table and insert it into the correct position in the left hand. To find the correct position for a card, we compare it with each of the cards already in the hand, from right to left Insertion Sort Works Pseudocode INSERTION-SORT(A) 1 for j = 2 to A.length 2 key = A[j] 3 // Insert A[j] into the sorted sequence A[1 .. j - 1 ]. 4 i = j - 1 5 while i > 0 and A[i] > key 6 A[i + 1] = A[i] 7 i = i - 1 8 A[i + 1] =  key Explanation iterates the elements from the 2nd position. compare the elements from right to left and swap them. each loop, we will have th...

2. Merge sort

 Merge sort Approach Divide      Divide the n-element sequence to be sorted  into two subsequences of n=2 elements each Conquer  Sort the two subsequences recursively using merge sort. Combine Merge the two sorted subsequences to produce the sorted answer. Merge MERGE(A,p,q,r) A - Array p,q and r - indices into array p <= q <= r A[ p .. q ] , A[ q .. r ] -->  A[ p .. r ] (venv) [velmuruganponnusamy@localhost merge-sort]$ cat merge-sort.py  def merge(A,p,q,r):     # pre-requisities in python     # array slicing and index and length function     L1 = A[ p:q ]     L2 = A[ q:r ]     print("Array - {0} ".format(A))     print( "*" * 80 )     # try without this step and identify why are we performing append stats     # depends on the ascending and descending, 999999999 needs to be changed     # if asc -> positive high value   ...
