Q: Suppose there is link list as follows:

Element : Address

5 : 1000

10 : 1500

15 : 2000

20 : 3000

You need to write a pseudo code to insert new node after (15) and set its value as

18. You can suppose the values of address.

A prime number is called an Additive prime if the sum of its digits is also a prime

number. Write a program that will display the N (user input) number of additive prime numbers

and displays the output in the following format:

Prime number

Sum of its digits

2

2

3

3

...

11

2

using user-defined functions

Sample output:

Enter an integer: 10

Prime number Sum of Digits

2 2

3 3

5 5

7 7

11 2

23 5

29 11
