Write the function most common substring(S,m) that receives a string S and an integer m and returns the substring
of length m that appears the most times in S and the number of times that substring appears. Your solution must
use a dictionary and run in time O(n). its using python

Some of my code so far:

def most_common_substring(S,n):

substring_list = [S[i:i+n] for i in range(len(S)-n+1)]

D = {w:0 for w in set(substring_list)}
