Please Solve in C. And do not use for, while, and do/while in your solution. Once again, please solve it without a WHILE LOOP.

Task - if the input is 34 , the checksum is 7(3+4); - if the input is 99 , the sum of its digits is 18(9+9), so the checksum is 9(1+8); - if the input is 99999999999 , the sum of its digits is 99(9+9+9+9+9+9+9+9+9+9+9), whose sum of digits is 18(9+9), so the checksum is 9(1+8). Requirements 1. Follow the format of the examples below. 2. Make sure your variables and parameters have the correct data types. 3. You must implement a recursive function to compute the checksum. This function can have only one parameter. 4. You are not allowed to use for, while, and do/while in your solution. Examples (your program must follow this format precisely) Example \#1 Input: 34 Checksum: 7 Example \#2 Input: 99 Checksum: 9 Example \#3 Input: 99999999999 Checksum: 9
