Hi all,

I have a string, which contains some special characters. From that i  
need to replace first 3 special chars with another special char.

Eg:-  
“ler-2545654-45-an-audience-with—corporate\_counsel” is original  
string.  
I need result as “ler/2545654/45/an-audience-with—corporate\_counsel”

Thank you,  
Priya

</div>

str = String.new(“ler-2545654-45-an-audience-with—  
corporate\_counsel”)  
=\> “ler-2545654-45-an-audience-with—corporate\_counsel”

str.sub(‘-’, ‘/’).sub(‘-’, ‘/’).sub(‘-’, ‘/’)  
=\> “ler/2545654/45/an-audience-with—corporate\_counsel”
