Write a programExercise 4/4Intermediate30 XP

The three most common words

Task

The file text.txt contains text (words separated by spaces and line endings, no punctuation). The program counts how many times each word occurs - ignoring upper and lower case - and prints the three most common words in lower case as word: count, from the most common. On equal counts alphabetical order decides. If there are fewer than three different words, it prints all of them.

For the file

pes macka pes

Pes vlk macka pes

the program prints:

pes: 4

macka: 2

vlk: 1

Examples

Input
```
(no input)
```
Expected output
```
pes: 4
macka: 2
vlk: 1
```

After you submit, 5 hidden tests will also check your solution: equal counts, one word, an empty file, the fourth word drops out, upper and lower case.

Python starts the first time you run code.

# spočítaj slová v súbore text.txt

Ctrl+Enter runs the program. Tab indents. Press Esc, then Tab, to leave the editor.
