I need to do a function which can split dot and equa by recursive.  
But I don't have any ideas to do on recursive.

This is the example of my strings

Member.certPm=PM Certification  
projects.risks.Index.flash\_downloading=Downloading report, please wait..

The numbers of dot it is different. I need to split these strings and  
set on hashes

Member =\> {certPm =\> PM Certification}  
projects =\> {risks =\> {Index =\> {flash\_downloading =\> Downloading  
report, please wait..}}}

Do you have any guide for me to do this?

Do I understand this correctly?

You have a string like this,

"projects.risks.Index.flash\_downloading=Downloading report, please wait.."

and you want to produce this,

projects =\> {risks =\> {Index =\> {flash\_downloading =\> Downloading  
report, please wait..}}}

Is that what you want to do?

Is this a homework question? Otherwise, why do you say you want to use a  
recursive algorithm, but then say you don't know anything about  
recursion?

A structure like :a =\> {:b =\> {:c =\> :d} } is nested. You do not need to  
use recursion to build it.

Almost guaranteed. Google the email address.
