Problem Statement

You are given the states of 3 death flags and 1 survival flag.
Determine whether the result is death or survival. The determination is made as follows.

  • If 2 or more death flags are raised, the result is death; if fewer than 2 are raised, the result is survival.
  • If the survival flag is raised, the result is survival regardless of the states of the death flags.

Input

$D_1$ $D_2$ $D_3$ $S$

$D_i\,$ is the state of death flag $\,i\,$ and $S\,$ is the state of the survival flag; each is given as $1\,$ or $\,0\,$.
$1\,$ means ON (the flag is raised) and $0\,$ means OFF (the flag is not raised).

Output

Print "DEAD" in the case of death and "SURVIVED" in the case of survival.
Print a newline at the end.
