Consider the following C code segment:
int x = 126, y = 105; do { if (x > y) x = x - y; else y = y - x; } while (x != y); printf("%d", x);
The output of the given C code segment is ____________. (Answer in integer)
Consider the following C program:
Suppose in a multiprogramming environment, the following C program segment is executed. A process goes into the I/O queue whenever an I/O related operation is performed. Assume that there will always be a context switch whenever a process requests an I/O, and also whenever the process returns from an I/O. The number of times the process will enter the ready queue during its lifetime (not counting the time the process enters the ready queue when it is run initially) is _________ (Answer in integer).
