const
maxn = 100;
var
a,b : array[0..maxn]of longint;
ans,i,j,D,E,F,DP,EP,H : longint;

begin
readln(D,E,F,DP,EP,H);
for i:=1 to D do begin
    DP:=DP div 2;
    a[i]:=DP;
end;
for i:=1 to E do begin
    EP:=EP div 2;
    b[i]:=EP;
end;
i:=1;j:=1;
while (i<=D)and(j<=E) do begin
    if a[i]>b[j] then inc(i)
    else if b[j]>a[i] then inc(j)
    else begin
      ans:=i+j-2;break;
    end;
end;
if ans<=H then writeln('YES') else writeln('NO');
end.
