## insert space character between every two character in a string

Hello,

I am trying to put a space between every two characters in an input string.  I only got the VI to work after the first 2 characters.  Can you help me get the space after every two (2) characters?

Thanks,

hiNi

## Re: insert space character between every two character in a string

Your input looks suspiciously like a hexadecimal number. Are you sure you need to be passing around strings instead of numbers?

If you really do need to work with strings, why not keep it as strings instead of converting down to bytes?

I was thinking more like this

Spoiler

There's an extra space at the end which can easily be deleted.

Easyer with string functions.

Using \V (not vertical whitespace) adds the spaces line by line and ignores the linefeeds.

You can get a little more performance (>10x?) if you don't use build array in a loop and avoid regex

You will need to pad an extra space at the end of the original string is its lenght is odd.

Depends on what's in the requirements doc

Just to break the monotony, here's yet another possibility.... 😄

(of course tweaks might be needed if the number of input characters is not even or if the last space is unwanted, for example)
