In this Company Logo problem, we need to develop a python program that read a string as input and then we need to print the number of occurrence of each character on the output screen in descending order.

## Problem solution in Python 2 programming.

```from sys import stdin

d = {}
for c in S:
if c in d:
d[c] += 1
else:
d[c] = 1

data = [[d[c],c] for c in d.keys()]
data.sort(key = lambda e: [-e,e])

for x in range(3):
print data[x], data[x]```

## Problem solution in Python 3 programming.

```#!/bin/python3

import math
import os
import random
import re
import sys
from collections import Counter

class OrderedCounter(Counter):
pass

if __name__ == '__main__':
[print(*c) for c in OrderedCounter(sorted(input())).most_common(3)]```

### Problem solution in pypy programming.

```# Enter your code here. Read input from STDIN. Print output to STDOUT
from collections import Counter
string = sorted(Counter(raw_input()).items(), key= lambda x: (-x,x))[:3]
print "\n".join(x+" "+str(x) for x in string)```

### Problem solution in pypy3 programming.

```from collections import Counter, OrderedDict

class OrderedCounter(Counter, OrderedDict):
pass
[print(*c) for c in OrderedCounter(sorted(input())).most_common(3)]```
