$($Optional$)$ TO DO #$3$: Remove the unrhymable words from the dictionary.

Some words are in a rhyme group by themselves. That means that nothing rhymes with them. We want to get rid of those before trying to make poems. You$$ll do this by implementing removeUnrhymables$().$

Use $$getKeys$()$ to get an array of all the keys.

Iterate through all the keys, retrieving the value $($linked list$)$ associated with each key.

If the length of the list is $1,$ that means there$$s only one word in the list: nothing rhymes with it$.$ Use $$Dictionary$.$remove$()$ to remove this entry.

If you$$re curious to see what words don$$t have rhymes $($at least according to the CMU pronunciation dictionary$),$ you could add a println to print out the words as you remove their corresponding entries. If you do this, don$$t forget to comment it out before you turn it in$.$

Here are a couple of tips:

Use casting $($Entry$),$ to make sure object values are transformed into what you need.

Use $.$equals$($key$)$ to compare strings to each other.

Example Input and Output

RhymingDict$$ can take $0,1$ or $2$ command line arguments.

The first argument is a seed for the random number generator. If you provide $0$ arguments this defaults to the current system time.

The second argument is the number of poems to generate. If $0$ or $1$ arguments are provided, this defaults to $3.$

For this command line:

java RhymingDict $204$

the output should look like:

If I were attuned then you'd be the muggy, And we'd both be marooned and never be buggy If I were tiber then you'd be the jonas, And we'd both be fiber and never be bonus Roses are flourish, violets are deeply. I am nourish and you are steeply. Roses are learners, violets are overturn. I am burners and you are sunburn.
