hello i am still new in ruby coding and i want to ask how can i apply these conditions in ruby and my case is that i receive different numbers from different countries like +962123456 or 00962123456 or 962123456.i have a csv file that has all country codes with their country name so i want to extract the country code from the number and then use hash to link it to csv file and add its country name field
and these aaare my conditions i want to implement in ruby
if (length(calling)==7)
calling="0" calling;
else if ((length(calling)\>8)&& (substr(calling,1,2) !="00") && (substr(calling,1,3) !="961") )
calling= calling;
else if (substr(calling,1,4) =="9612")
calling ="0" substr(calling,4) ;
else calling=calling;
if (length(called)==7)
called="0" called;
else if ((length(called)\>8)&& (substr(called,1,2) !="00") && (substr(called,1,3) !="961") )
called= called;
else if (substr(called,1,4) =="9612")
called ="0" substr(called,4) ;
else called=called;
if (substr (calling,1,3)=="961")
calling=substr (calling,4);
while(substr(calling,1,1)=="0")
calling = substr(calling,2);
