Write a program to read a string / sentence and output the number of times each word occurs in the entire text. At the end, the output should be sorted into ascending order words along with usage of words. You may assume that the entire text is in capitals (you may also convert in capitals for your betterment) and each word is followed by a blank space except the last one, which is followed by a full stop. Let there be at the most 50 words in the text.

Test your program for the given sample data and also some other random data:

SAMPLE DATA:

Input:
YOU ARE GOOD WHEN YOUR THOUGHTS ARE GOOD AND YOUR DEEDS ARE GOOD.

Output:

WordsWord Count
And1
Are3
Deeds1
Good3
Thoughts1
When1
You1
Your2

Input:
IF YOU FAIL TO PLAN YOU ARE PLANNING TO FAIL.

Output:

WordsWord Count
Are1
Fail2
If1
Plan1
Planning1
To2
