Write a program to calculate the frequency of each word

Prompt the user for a filename

Make a dictionary of the words in the file

The keys are the words

The values are the counts of how many times the word appears in the file

When reading the file, convert everything to lowercase so $$the$$ and $$The$$ count as the same word

Note that the test files will only contain words and whitespace. No punctuation

Print the words in alphabetical order

Print the words again in descending order of frequency

Sample Run #$1($bold$,$ underlined text is what the user types$)$:

File? file$1.$txt

Words in alphabetic order:

and $2$

away $1$

cat $1$

cow $1$

diddle $2$

dish $1$

dog $1$

fiddle $1$

hey $1$

jumped $1$

moon $1$

over $1$

ran $1$

see $1$

spoon $1$

sport $1$

such $1$

the $7$

Words in descending frequency:

$1$ to

$1$ such

$1$ sport

$1$ spoon

$1$ see

$1$ ran
