HELP!!!

Written in C

#include

#include

extern char **environ;

void output(char *a[], char *b[]) {

int c = atoi(a[0]);

for (int i = 0; i < c && b[i]; ++i) {

printf("%s", b[i]+2);

}

}

void main(int argc, char *argv[]) {

switch (argc) {

case 1:

for (int i = 0; environ[i]; ++i) {

printf("%s", environ[i]);

}

break;

default:

output(argv + 1, environ + 2);

exit(argc);

}

}

After executing the command $ ./m0 (assuming that the code above was compiled with $ gcc m0.c -o m0), suppose that the output is

A=3

B=2

C=3

D=1

E=1

What is the output of executing this command $ ./m0 2 3 4 5?

(atoi(str) converts the string argument str to an integer)
