Problem B
Bachelor's Thesis

SoCCat the Undergraduate is a very studious cat. Currently, SoCCat is writing their Bachelor’s Thesis!

For SoCCat’s Final Year Project, SoCCat will write a thesis studying the behaviour of a particular operation: the cat-split.

Initially, suppose SoCCat has an array of $n$ integers $a_1, a_2, \ldots , a_ n$, and an integer $k$ ($1 \leq k \leq n$). In one cat-split operation, SoCCat will do all of the following in order:

1. Choose any subsequence of $a$ which consists of exactly $k$ elements.

2. Delete the chosen subsequence from the array $a$.

3. Append the values of the chosen subsequence to the beginning of the array $a$ in reverse order.

For example, for an array $a = [5, 1, 4, 2, 3]$ and integer $k = 3$, SoCCat can choose the subsequence $[1, 4, 3]$. Next, SoCCat will remove the elements $[1,4,3]$ from $a$, after which the array will become $[5,2]$. Finally, SoCCat will prepend the elements $[1, 4, 3]$ in reverse order, after which the array will become $[3,4,1,5,2]$.

SoCCat is interested in knowing the minimum possible number of inversions in the array $a$ after doing the cat-split operation between $0$ up to $100\, 000$ times. As SoCCat is busy studying other properties of the cat-split operation, they turn to you for help!

Note that you do not have to minimize the number of cat-split operations, only the number of inversions in the resulting array.

As a reminder,

• $b_1, b_2, \ldots , b_ k$ is a subsequence of $a$ if and only if $b_1, b_2, \ldots , b_ k$ can be obtained from $a$ by deleting zero or more elements from it without changing the order of the remaining elements.

• The inversion of an array $a$ is equal to the number of pairs $(i, j)$ such that $i < j$ and $a_ i > a_ j$.

Input

The first line of input contains two integers $n$ and $k$, denoting the number of elements in the array $a$ and the specific number of elements chosen in the subsequence for each cat-split operation ($1 \leq n \leq 100$; $1 \leq k \leq n$).

The following line contains $n$ integers $a_1, a_2, \ldots , a_ n$, denoting the elements of the array $a$ ($1 \leq a_ i \leq 100$).

Output

In the first line, output the minimum possible number of inversions in the resulting array after doing the cat-split operation between $0$ up to $100\, 000$ times.

In the second line, output $l$, denoting the number of cat-split operations SoCCat should perform to obtain the minimum number of inversions in the resulting array ($0 \leq l \leq 100\, 000$). You do not have to minimize $l$.

Each of the following $l$ lines should contain a binary string of length $n$, denoting the subsequence SoCCat should choose for that particular operation. The $i$-th character of the binary string should be 1 if the $i$-th element of the array is chosen for the subsequence, and 0 otherwise. Note that each binary string should therefore contain exactly $k$ 1’s.
