HW.1.
A student identification number consists of 5 digits and a control digit. Control digit is calculated using the first 5 digits.

For example:
518894 is a valid ID number.

The control digit is calculated as follows:

Suppose ABCDE is an ID number. To calculate control digit, firstly,

A is multiplied by 2, and the digits of the product is summed to get X

C is multiplied by 2, and the digits of the product is summed to get Y

E is multiplied by 2, and the digits of the product is summed to get Z

Then, X+B+Y+D+Z is calculated to get SUM,

Lastly the control digit is calculated by subtracting SUM from the closest number which is multiple of 10 and greater than SUM.

For example: if ID=51889

  2x5=10 ---> X=1+0 =1

  2x8=16 ---> X=1+6 =7

  2x9=18 ---> X=1+8 =9

SUM = 1+1+7+8+9 = 26

the closest number which is multiple of 10 and greater than SUM is : 30

so the control digit is 30-26 : 4

Write a complete C program which inputs 5 digits identification number,  calculates and prints the control digit.

Notes:

Use suitable data types

there should not be spaces between the digits in the input
