Given a code snippet below?

#define PERMS  (S_IRUSR | S_IWUSR | S_IRGRP | S_IWGRP | S_IROTH | S_IWOTH)
int main() 
{
    int fd1, fd2;
    umask(0);
    fd1 = open(“file1”, O_CREAT | O_RDWR, PERMS)
    umask(S_IRGRP | S_IWGRP | S_IROTH | S_IWOTH);
    fd2 = open(“file2”, O_CREAT | O_RDWR, PERMS)
    return 0;
}

The newly created files file1 and file2 will have the permissions respectively
