Solve the programming task below in a Python markdown code block.
An English text needs to be encrypted using the following encryption scheme. 

First, the spaces are removed from the text. Let $L$ be the length of this text. 

Then, characters are written into a grid, whose rows and columns have the following constraints:

$\lfloor\sqrt{L}\rfloor\leq row\leq column\leq\lceil\sqrt{L}\rceil,\text{where}\lfloor x\rfloor\text{is floor function and}\lceil x\rceil\text{is cell function}$ 

Example  

$s=\textbf{if man was meant to stay on the ground good would have given us roots}$  

After removing spaces, the string is $54$ characters long.  $\sqrt{54}$ is between $7$ and $8$, so it is written in the form of a grid with 7 rows and 8 columns.

sroots

Ensure that $rows\times columns\geq L$   
If multiple grids satisfy the above conditions, choose the one with the minimum area, i.e. $rows\times columns$.  

The encoded message is obtained by displaying the characters of each column, with a space between column texts. The encoded message for the grid above is:

Create a function to encode a message.

Function Description  

Complete the encryption function in the editor below.  

encryption has the following parameter(s):  

string s: a string to encrypt  

Returns  

string: the encrypted string  

Input Format

One line of text, the string $\boldsymbol{\mathrm{~S~}}$

Constraints

$1\leq\ \text{length of}\ s\leq81$ 

$\boldsymbol{\mathrm{~S~}}$ contains characters in the range ascii[a-z] and space, ascii(32).
