 Need Help??

My first try at golf:

```sub b {
\$M = scalar keys %t;
\$m = \$M *= \$M;
foreach  ( keys %t ) {
\$r = c( \$_ );
(\$m,\$n) = (\$r, \$_) if (\$r < \$m );
}
\$n;
}

sub c {
@s=@_;
%b  = ( \$s[0] => \$b=\$sum=0 );
while ( @s > 0 ) {
\$b ++;
@s = grep {  ! exists( \$b{\$_}  ) }
map { @{\$t{\$_}} } @s;
@b{ @s } = (\$b) x scalar(@s);
\$sum += \$b * scalar(@s);
return \$M if \$sum >  \$m
}
\$sum;
}

works for graphs too, I think.

Update: I can write that down in 196:

```sub b{\$M=\$m=@_*@_;for(keys %t){\$r=c(\$_);(\$m,\$n)=(\$r,\$_)if(\$r<\$m)}\$n}su
+b c{%b=(\$_[0]=>\$b=\$sum=1);while(@_){\$b++;@_=grep{!\$b{\$_}}map{@{\$t{\$_}
+}}@_;@b{@_}=(\$b)x@_;\$sum+=\$b*@_;return\$M if\$sum>\$m}\$sum}

slower but shorter: down to 177:

```sub b{\$M=\$m=@_*@_;for(keys %t){\$r=c(\$_);(\$m,\$n)=(\$r,\$_)if(\$r<\$m)}\$n}su
+b c{%b=(\$_[0]=>\$b=\$sum=1);while(@_){\$b++;@_=grep{!\$b{\$_}}map{@{\$t{\$_}
+}}@_;@b{@_}=(\$b)x@_;\$sum+=\$b*@_}\$sum}

I never new how hard obfuscation is! </code>
