#include <stdio.h>

void on_button() {
    printf("Button Pressed");
}
void on_timer() {
    printf("Timer Expired");
}
void on_uart() {
    printf("UART Received");
}
void on_power() {
    printf("Power On");
}
void on_error() {
    printf("Error Detected");
}

void outer_range() {
    printf("Unhandled Event");
}

// Write your event dispatcher logic here
void handle_event(int event_code) {
    void (*fp[6])() = {on_button, on_timer, on_uart, on_power, on_error, outer_range};
    if(event_code>4 || event_code<0) {
        fp[5]();
    }
    else {
        fp[event_code]();
    }
    
    // Your logic
}

int main() {
    int event;
    scanf("%d", &event);
    handle_event(event);
    return 0;
}
