#include<stdio.h>
int main()
{
    int n,a[10],i,j,count=0,maxcount=0,maxvalue=0;

import collections
Numbers = [234, 423, 4, 67, 22, 22]

print(Numbers)

data = collections.Counter(Numbers)
data_list = dict(data)

print(data_list)

max_value = max(list(data.values()))
mode_val = [num for num, freq in data_list.items() if freq == max_value]
if len(mode_val) == len(Numbers):
   print("No mode found")
else:
   print("The Mode of the list is : " + ', '.join(map(str, mode_val)))

from statistics import mode

theList = [1, 2, 2, 3, 3, 3, 4, 5, 5, 5, 5, 5, 5, 6]
print("\n{:19s}{:>3d} {}".format("The int list has:", len(theList), "elements..."))
print("{:19s}{:>3d} {}".format("Mode is:", mode(theList), "(mode = most frequent item)")

theList = ["Dog", "Cat", "Spider", "Snake", "Dog", "Dog", "Bear"]
print("\n{:19s}{:>3d} {}".format("Animal's list has:", len(theList), "elements..."))
print("{:16s}{:>6s} {}".format("Mode is:", mode(theList), "(mode = most frequent item)"))
