FACUP - The FA cup

The FA Cup is the oldest footbal cup. All the matches will play on knock-out rule. There are 2^N teams in the cup playing in N rounds. There are 2^(N-1) matches in the first round and 2^(N-1) winners advances to the second round. And so on. Until there is only a team left. This is the champion.

Matches in the first round are numbered as 1 to 2^(N-1): team 1 vs team 2, team 3 vs team 4, ..., and team (2^N-1) vs team 2^N. Matches in the second round are: match 1's winner vs match 2's winner, ..., match 2^(N-2)'s winner vs match 2^(N-1) winner.

Matches in the second round are numbered as 1 to 2^(N-2) and matches in the third round are: match 1's winner vs match 2's winner, ..., match 2^(N-3)'s winner vs match 2^(N-2) winner.

There is no tie in a game (if a game is tied at the end of regulation time it goes into extra time and/or penalty shootout). Given the fixtures and result's probability of every matches. Your task is to sort the teams decreasingly according to the chance of becoming champion.

Input

  • The first line containg an integer N (1 ≤ N ≤ 8).
  • In the next lines there is a matrix P of size (2^N) * (2^N) containing integers in the interval [0, 100]. P[x, y] is the percentage that team x can defeat team y. The sum of P[x, y] and P[y, x] is always 100 and P[x, x] = 0 for all x.

Output

Print out 2^N lines. Each line contains the index of a team sorted in deceasing order according to the chance of become champion for a team. If there are two teams with the same chance of becoming champion, print the team with smaller index first.

Description

Let the teams be MANCHESTER, FULHAM, ARSENAL, CHELSEA. The giants MANCHESTER, ARSENAL, CHELSEA all have 90% winning chance when vs FULHAM. When the three teams plays with one another, the winning chance is equally 50%-50%. However, because MANCHESTER has advantages in playing schedule, they have the highest chance to become champion.

MANCHESTER is the champion if:

- MANCHESTER wins over FULHAM, MANCHESTER wins over ARSENAL and ASERNAL wins over CHELSEA. This probability is 90% * 50% * 50% = 22.5%

- MANCHESTER wins over FULHAM, MANCHESTER wins over CHELSEA and CHELSEA wins over ARSENAL. This probability is 90% * 50% * 50% = 22.5%

MANCHESTER has a total of 45% chance to become FA Cup's winner.

ARSERNAL wins FA cup if:

- ARSENAL wins over CHELSEA, ARSENAL wins over MANCHESTER, MANCHESTER wins over FULHAM. This probability is 50% * 50% * 90% = 22.5%

- ARSENAL wins over CHELSEA, ARSENAL wins over FULHAM, FULHAM wins over MANCHESTER. This probability is 50% * 90% * 10% = 4.5%

ARSENAL has a total of 27% chance to become FA Cup's winner.

CHELSEA's chance to win FA Cup is calculated in the same way as ARSENAL and is also 27%.

FULHAM wins FA Cup if:

- FULHAM wins over MANCHESTER, FULHAM wins over ARSENAL and ARSENAL wins over CHELSEA. This probability is 10% * 10% * 50% = 0.5%

- FULHAM wins over MANCHESTER, FULHAM wins over CHELSEA and CHELSEA wins over ARSENAL. This probability is 10% * 10% * 50% = 0.5%

So FULHAM has only 1% chance to become FA Cup's winner.
