Hello Guys!

In this Video, we going to
do merge sort in Python

Video Language:- Tamil
----------------------------------
ALGORITHM:
1.Create a function named mergesort
2. Find the mid of the list
3. Assign lefthalf = alist[:mid] and righthalf = alist[mid:]
4. Initialise i=j=k=0
5. while i (less than ) len(lefthalf) and j (less than) len(righthalf), perform the following
if lefthalf[i] (less than) righthalf[j]:
alist[k]=lefthalf[i]
Increment i
else
alist[k]=righthalf[j]
Increment j
Increment k
6. while i (less than) len(lefthalf),perform the following
alist[k]=lefthalf[i]
Increment i
Increment k
7. while j (less than) len(righthalf), perform the following
alist[k]=righthalf[j]
Increment j
Increment k
8. Print the sorted list

PROGRAM:
def mergeSort(alist):
print("Splitting ",alist)
if len(alist)(greater than)1:
mid = len(alist)//2
lefthalf = alist[:mid]
righthalf = alist[mid:]

mergeSort(lefthalf)
a=[]
n=int(input('Enter upper limit:'))
for i in range(n):
#alist = [54,26,93,17,77,31,44,55,20]
mergeSort(a)
print(a)
