Write a function referencing the parameter $"$dct$"$ to perform the following operations. Run the function using the dictionary called "inventory" as an argument.

Start by printing the original dictionary:

$\{\text{'}$iphone$\text{'}$: $40,$ 'ipad': $17,$ 'macbook': $12,$ 'monitor': $5\}$

a$.$ Add the key value pair "stylus": $16$ and print the result.

$\{\text{'}$iphone$\text{'}$: $40,$ 'ipad': $17,$ 'macbook': $12,$ 'monitor': $5,$ 'stylus': $16\}$

b$.$ Change the ipad inventory to $19$ then print the result.

$\{\text{'}$iphone$\text{'}$: $40,$ 'ipad': $19,$ 'macbook': $12,$ 'monitor': $5,$ 'stylus': $16\}$

c$.$ Remove the key value pair, "monitor": $5$ then print the result.

$\{\text{'}$iphone$\text{'}$: $40,$ 'ipad': $19,$ 'macbook': $12,$ 'stylus': $16\}$

d$.$ Extract each of the values in the dictionary and add them to the list called counts. Print the counts list.

$[40,19,12,16]$
