[Question]
  [
We are going to bring down an imaginary building with a series of explosions. Our building is a 5x5 matrix of integers ranging 1-9, each representing a single brick.
The challenge is to set of a series of explosions to bring down our building as much as we can, why not! Each brick that is connected (horizontally, vertically, diagonally) to a copy of itself will represent a payload that is going to explode in the next detonation. The bricks above those that are blown to bits will fall down. We will continue these steps untill we cannot demolish the building any further:
Look at the 'building' to find connected copies of integers for an explosion, set of the explosion to let bricks above the explosion fall down to create a new *array of digits*. If an explosion occured make sure to backfill your 'building' with a zero to represent rising smoke from the ashes. Though, extra imaginary digital kudos if you used actual [clouds](https://www.compart.com/en/unicode/U+2601), e.g:

Your final output, the result of this challenge, should represent the ruins after the last possible detonation with the aforementioned smoke rising from the ashes.
In the case of no possible explosions, sadly output == input. In the occurence of a single big explosion (or multiple explosions for that matter) to bring the whole building down, the result is simply an array of clouds.

Input and output are 2D numerical arrays, with `0` for smoke in the output.

### How it works
You can see a convolution coming, can't you?
```
12:"     % For each n in [1 2 ... 12]. 12 is a bound on the number of explosions
  9:"    %   For each k in [1 2 ... 9]
    t    %     Duplicate the numerical 2D array (A). Triggers implicit input the
          %    first time
    @=   %     Compare element-wise with k. Gives a zero-one 2D array (B)
    t    %     Duplicate
    3Y6  %     Push [1 1 1; 1 0 1; 1 1 1]. This defines the neighbourhood
    Z+   %     2D convolution, maintaining size. This counts, for each entry in
         %     (B), how many ones there are in its neighbourhood
    *    %     Multiply, element-wise. This counts, only for each entry in (B)
         %     equal to one, how many ones it has around
    ~    %     Negate. This gives zero for entries that are going to disappear,
         %     one otherwise
    *    %     Multiply by (A), element-wise. This sets the required entries to
         %     zero 
  ]      %   End
  tg     %   Duplicate. Convert to logical: non-zero values become one
  &S     %   Sort each column, and output the indices that correspond to the
         %   sorting. Gives a 2D array containing a permutation of [1 2 ... 5]
         %   in each column (C). This sorting corresponds to sending the zeros
         %   to the top of each column
  5:     %   Push [1 2 ... 5]
  q5*    %   Subtract 1, multiply element-wise by 5. Gives [0 5 10 15 20]
  +      %   Add to (C) with implicit expansion. This gives the linear indices 
         %   that will send zeros to the top of each column
  )      %   Reference indexing
         % End (implicit)
         % Display (implicit)

## How?
We use the same recursive function to process two distinct steps:
1. Fill an array of strings representing the updated columns of the matrix without removed cells. Then convert this array back to a matrix.
2. Test whether a given cell should be removed.
### Step 1
The variable \$V\$ is initially set to an empty array and the variables \$X\$ and \$Y\$ are undefined.
For each cell at \$(x,y)\$ with value \$v\$, we insert the result of the second step at the beginning of \$V[x]\$ (coerced to an empty string if it's still undefined):
```
V[x] = f(m, v, x, y) + [V[x]]
```
Once all cells have been processed, we transpose the strings stored in \$V\$ to build the new matrix with each column filled with leading 0's wherever needed:
```
V.map((s, j) =>
  m.map((r, i) => r[j] = ~~s[4 - i])
)
```
If the matrix is unchanged, we stop and return it. Otherwise, we do a recursive call at step 1.
### Step 2
The variable \$V\$ is set to the value of the cell being tested and the variables \$X\$ and \$Y\$ hold its coordinates.
We walk through each cell at \$(x,y)\$ and set \$V\$ to an empty string as soon as a neighbor cell with the same value \$v\$ is detected. A neighbor cell is a cell whose squared Euclidean distance with the reference cell is either \$1\$ or \$2\$. This is tested with a bitmask:
```
6 >> (X - x) ** 2 + (Y - y) ** 2 & V == v
```
NB: Because the matrix is \$5\times5\$, the maximum squared Euclidean distance is \$32\$, in which case the shift amount will wrap to \$0\$. Fortunately, this will still work as expected.
Once all cells have been processed, we simply return \$V\$.
