Write a program that prompts the user to input a dictionary, calculates the sum of its

values using a function $($this function will take the dictionary as argument and returns the

sum of all the values in the dictionary$),$ and prints the result.

Sample Input:

Enter the number of key$-$value pairs in the dictionary: $4$

Enter key: a

Enter value for key $$a$$ : $10$

Enter key : b

Enter value for key $$b$$ : $20$

Enter key : c

Enter value for key $$c$$ : $30$

Enter key : d

Enter value for key $$d$$ : $40$

Sample Output:

The sum of values: $100$
