#define HALF$\_$CENT $50$

char a$\_$list$[$ HALF$\_$CENT $],$ b$\_$list$[$ HALF$\_$CENT $],$ a$\_$char $=\text{'}$v$\text{'}$;

int nums$[$ A$\_$SIZE $],$ vals$[$ A$\_$SIZE $],$ i $=1$;

Answer True if the statement is valid, False otherwise: for $($i $=1$; i $<=$ A$\_$SIZE; $++$i$)$

nums$[$ A$\_$SIZE $-$ i $]=$ i;
