Problem Statement

There is a grid with H rows from top to bottom and W columns from left to right. Let (i, j) denote the square at the i-th row from the top and j-th column from the left.
The squares are described by characters C_{i,j}. If C_{i,j} is ., (i, j) is empty; if it is #, (i, j) contains a box.

For integers j satisfying 1 \leq j \leq W, let the integer X_j defined as follows.

• X_j is the number of boxes in the j-th column. In other words, X_j is the number of integers i such that C_{i,j} is #.

Find all of X_1, X_2, \dots, X_W.

Constraints

• 1 \leq H \leq 1000
• 1 \leq W \leq 1000
• H and W are integers.
• C_{i, j} is . or #.

Sample Output 1

1 2 0 3

In the 1-st column, one square, (1, 1), contains a box. Thus, X_1 = 1.
In the 2-nd column, two squares, (2, 2) and (3, 2), contain a box. Thus, X_2 = 2.
In the 3-rd column, no squares contain a box. Thus, X_3 = 0.
In the 4-th column, three squares, (1, 4), (2, 4), and (3, 4), contain a box. Thus, X_4 = 3.
Therefore, the answer is (X_1, X_2, X_3, X_4) = (1, 2, 0, 3).

Problem Statement

N people, person 1, person 2, \ldots, person N, are playing roulette. The outcome of a spin is one of the 37 integers from 0 to 36. For each i = 1, 2, \ldots, N, person i has bet on C_i of the 37 possible outcomes: A_{i, 1}, A_{i, 2}, \ldots, A_{i, C_i}.

The wheel has been spun, and the outcome is X. Print the numbers of all people who have bet on X with the fewest bets, in ascending order.

More formally, print all integers i between 1 and N, inclusive, that satisfy both of the following conditions, in ascending order:

• Person i has bet on X.
• For each j = 1, 2, \ldots, N, if person j has bet on X, then C_i \leq C_j.

Note that there may be no number to print (see Sample Input 2).

Constraints

• 1 \leq N \leq 100
• 1 \leq C_i \leq 37
• 0 \leq A_{i, j} \leq 36
• A_{i, 1}, A_{i, 2}, \ldots, A_{i, C_i} are all different for each i = 1, 2, \ldots, N.
• 0 \leq X \leq 36
• All input values are integers.

The wheel has been spun, and the outcome is 19. The people who has bet on 19 are person 1, person 2, and person 4, and the number of their bets are 3, 4, and 3, respectively. Therefore, among the people who has bet on 19, the ones with the fewest bets are person 1 and person 4.

The wheel has been spun and the outcome is 0, but no one has bet on 0, so there is no number to print.

Problem Statement

There are M sets, called S_1, S_2, \dots, S_M, consisting of integers between 1 and N.
S_i consists of C_i integers a_{i, 1}, a_{i, 2}, \dots, a_{i, C_i}.

There are (2^M-1) ways to choose one or more sets from the M sets.
How many of them satisfy the following condition?

• For all integers x such that 1 \leq x \leq N, there is at least one chosen set containing x.

Constraints

• 1 \leq N \leq 10
• 1 \leq M \leq 10
• 1 \leq C_i \leq N
• 1 \leq a_{i,1} \lt a_{i,2} \lt \dots \lt a_{i,C_i} \leq N
• All values in the input are integers.

Problem Statement

A region has N towns numbered 1 to N, and M roads numbered 1 to M.

The i-th road connects town A_i and town B_i bidirectionally with length C_i.

Find the maximum possible total length of the roads you traverse when starting from a town of your choice and getting to another town without passing through the same town more than once.

Problem Statement

There is a sequence A = (A_0, A_1, \dots, A_{N - 1}) with N = 2^{20} terms. Initially, every term is -1.

Process Q queries in order. The i-th query (1 \leq i \leq Q) is described by an integer t_i such that t_i = 1 or t_i = 2, and another integer x_i, as follows.

• If t_i = 1, do the following in order.
  1. Define an integer h as h = x_i.
  2. While A_{h \bmod N} \neq -1, keep adding 1 to h. We can prove that this process ends after finite iterations under the Constraints of this problem.
  3. Replace the value of A_{h \bmod N} with x_i.
• If t_i = 2, print the value of A_{x_i \bmod N} at that time.

Here, for integers a and b, a \bmod b denotes the remainder when a is divided by b.

Constraints

• 1 \leq Q \leq 2 \times 10^5
• t_i \in \{ 1, 2 \} \, (1 \leq i \leq Q)
• 0 \leq x_i \leq 10^{18} \, (1 \leq i \leq Q)
• There is at least one i (1 \leq i \leq Q) such that t_i = 2.
• All values in input are integers.

Sample Output 1

1048577
-1

We have x_1 \bmod N = 1, so the first query sets A_1 = 1048577.

In the second query, initially we have h = x_2, for which A_{h \bmod N} = A_{1} \neq -1, so we add 1 to h. Now we have A_{h \bmod N} = A_{2} = -1, so this query sets A_2 = 1.

In the third query, we print A_{x_3 \bmod N} = A_{1} = 1048577.

In the fourth query, we print A_{x_4 \bmod N} = A_{3} = -1.

Note that, in this problem, N = 2^{20} = 1048576 is a constant and not given in input.
