Write a complete ANSI C code using recursion to calculate the $sum(s)$ of the digits of an integer number (i) consisting of maximum 5 digits. For example, (1) = if $i=12345$, then your program should print $s=15$, (2) if $ i=457$, then $s=16$.

An operating system contains three resource classes. The number of resource units in these classes are $7, 7\ \text{and} \ 10$ ... safe? Justify. If process $P_1$ now requests $(1,1,0)$ resources, then what will be the status of the new state?
