Consider the following C program :

#include <stdio.h>
void stringcopy(char *, char *);
int main( ) {
    char a[30] = "@#Hello world!";
    stringcopy(a,a+2);
    printf("%s\n", a);
    return 0;
}
void sringcopy(char *s, char *t) {
    while(*t)
        *st++ = *t++;
}

Which ONE of the following will be the output of the program?

int x = 126, y = 105;
do{
   if(x > y) x = x - y;
   else y = y - x;
}while(x!=y);
printf('%d", x);
