Problem

Gahui is watching the annual character election. After the election, the top 16 characters receive large benefits for one year. For that reason, fans vote passionately to get their favorite characters into the top 16. At least one Cinderella appears in every election, a character who reaches the top 16 with an outstanding result.

Election results are announced twice: a preliminary result and a final result. For character $x$ :

Character $x$ got $p_x$ votes in the preliminary result.
Character $x$ got $r_x$ votes in the final result.

$v_x$ is defined as $p_x / r_x$ . The type of character $x$ is determined by the value of $v_x$ .

If $v_x < 0.2$ , the type of character $x$ is weak.
If $0.2 \le v_x < 0.4$ , the type of character $x$ is normal.
If $0.4 \le v_x < 0.6$ , the type of character $x$ is strong.
If $0.6 \le v_x$ , the type of character $x$ is very strong.

Given the preliminary and final results of character $x$ , print the type of character $x$ .

Input

The input is one line with two integers $p_x$ and $r_x$ , separated by a space.

Output

Print the type of character $x$ .

Constraints

$1 \le p_x \le 60\,000$
$1 \le r_x \le 250\,000$
$p_x \le r_x$

Hint

Who can foresee such an unexpected outcome when the final result deviates significantly from the preliminary result?
