Your Student ID is a 9-digit number. You are going to hash it to a 4-digit integer using the following steps: . Separate every three digits of the ID. We name them L (for the three left-most digits), M (for the three middle digits) and R (for the three right-most digits). . Compute the summation of the digits of each L, M and R, and store them in the same locations, L, M and R, respectively. For instance, if L = 123, then L = 1+2+3 = 6. Or, for instance, if M = 676, then M=6+7+6 = 19. If each of L, M and R is one digit. We are done in this step. However, if any of them is greater than 9, then we should repeat the digits summation until we reach to a single-digit number. For instance, in the above example, M = 676, and therefore, M beomes 19, which is greater than 9. We repeat the digits summation on M. Because M= 19, therefore, M = 1 +9= 10. Again, M is greater than 9. We repeate the digits summation on M. M= 10, therefore, M= 1 + 0 = 1. Now we stop. After this repetative step, cach of L, M and R is only a single digit. . Compute the summation of L, M and R, and put it into S. Same as the previous step, if S is greater than 9, we repeatedly do the digits summation until S becomes only a single-digit number. For instance, if at the end of the previous step L = 6, M = 7, and R = 1, then S = 6+ 7+1 = 14. Now, S is greater than 9. Therefore, we repeat the digits summation on the digits of S. S = 14, thus, S = 1 +4= 5. Now, S is a single-digit number and we stop. . The final four-digit hash value will be Hash = M* 1000+S * 100 +L * 10 + R. Write a C program that will create the hash value of a Student ID that is entered by the user. Note that the ID should be a 9-digit integer, but you don't need to do any input validity check. We assume that the user will enter correct input. Note: The digits separation should be done programatically. However, you should only use math operations to separate the digits. No function should be used for this purpose. Function should be used for this purpo Sample execution: Please enter a 9-digit integer: 108965676 The hash value of your ID(108965676) is 2391 Explanation: ID= 108965676 L= 108 M = 965 R 676 L= 1 + 0 +8=9 M=9+ 6+ 5 = 20 M-2 + 0 2 R= 6 + 7 + 6 = 19 R-1 +9 10D R-1 + 0 = 1 S=L+M+R= 9+ 2 + 1 = 12 S-1 + 2 = 3 Hash = M* 1000 + S 100+ L + 10 + R - 2 - 1000+ 3 * 100+ 9 + 10 + 1 2391 5
