4. An interesting problem in number theory is sometimes called the "necklace problem". This problem begins with 22 single-digit numbers. The next number in the sequence is obtained by adding the 2 numbers together and dropping the "10's" digit (i.e. 8 9 17, drops the 1 to get 7). This can be done by modding (remainder operator) the answer by 10. The process continues until the necklace closes that is, it returns to the original 2 numbers. Here is an example that starts with the numbers 1 and 8: 1, 8, 9, 7, 6, 3, 9, 2, 1, 3, 4, 7, 1, 8. Write a C program that prompts the users for two single digit integers and then displays the sequence and the number of steps taken. Check for valid inputs (negative values). Refer to the sample output below. Sample Run: Enter a start digit 1 Enter a stop digit 8 Sequence 1 89 7 6 39 2 1 3 4 7 1 8 Steps taken 12 Name the program: N where XX are your initials
