What is wrong with the following code:

$($Explain your choice in calculation sheet$)$

$//$

int led $=13$;

void setup$()\{$

pinMode$($led$,$ INPUT$)$;

$\}$

void loop$()\{$

digitalWrite$($led$,$ HIGH$)$;

delay$(1000)$;

digitalWrite$($led$,$ LOW$)$;

delay$(1000)$;

$\}$

delay $(1000)$ must be changed to delay$(1)$

The led PIN should be configured as OUTPUT

void setup$()$ should be swapped with void loop$()$

delay$(1000)$ must be changed to delay$(100)$
