##### Short Problem Definition:

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.

##### Complexity:

time complexity is `O(n)`

space complexity is `O(1)`

##### Execution:

You do not need to create all the arrays. Just work with an offset and array slices.

##### Solution:

```
#!/usr/bin/py
from math import sqrt, floor, ceil
if __name__ == '__main__':
s = raw_input().replace(" ", "")
columns = int(ceil(sqrt(len(s))))
for c in xrange(columns):
print s[[c::columns]],
```
