Assume that `file1` exists and is empty. Consider what happens when the program `arrow` is run.```c/* arrow.c */int main(void) { close(1); open("file1", 1); printf("Madman versus Arrow!"); fflush(stdout); close(1); if (fork() > 0) { wait(NULL); execlp("./batman", "./batman", (char*)0); } else execlp("./merlin", "./merlin", (char*)0); return 42;}```Here are the two programs called by `arrow`:```c/* batman.c */int main(void) { open("file1", 1); printf("Batman"); fflush(stdout); close(1); return 24;}/* merlin.c */int main(void) { open("file1", 1); printf("Merlin"); fflush(stdout); close(1); return 24;}```After the program runs, what does the command `echo $?` produce?`echo $?` produces:[ ]Character for character, `file1` contains exactly the characters:[ ]

After the program runs what does the command echo $ ?produce? The correct answer is 24 as shown in…
