Fix the following UCLID5 code using the compiler feedback provided below.

```

model leader_election_protocol
  type pid_t = int;
  type msg_t = int;

  const n : pid_t;

  record process_state_t {
    id : pid_t;
    channel : array [pid_t][msg_t];
    leader : boolean;
  }

  var processes : array [pid_t][process_state_t];

  init {
    for pid : pid_t :: processes[pid].id = pid;
    for pid : pid_t :: processes[pid].leader = false;
    for pid : pid_t :: processes[pid].channel[pid] = processes[pid].id;
  }

  define next_pid(pid: pid_t) : pid_t {
    return (pid % n) + 1;
  }

  procedure send_msg(src_pid : pid_t, msg : msg_t)
  {
    processes[next_pid(src_pid)].channel[src_pid] = msg;
  }

  procedure receive_msg(pid : pid_t) returns (msg : msg_t)
  {
    return processes[pid].channel[pid];
  }

  procedure process_action(pid : pid_t)
  {
    var m : msg_t;
    m = receive_msg(pid);
    if (m = processes[pid].id) {
      processes[pid].leader = true;
    } else if (m > processes[pid].id) {
      send_msg(pid, m);
    }
  }

  next {
    for pid : pid_t :: process_action(pid);
  }

  control {
    init;
    while (true) {
      next;
    }
  }
end
```

Reply with your UCLID5 code inside one unique code block.

I can definitely do that! Here is the UCLID5 code:
