Dear Friends,

1. Given a string containing an Excel-like range specifier like this:  
“C5:E8”, generate an array of all the cells in the array.

In this case, the output should be something like this…

[“C5”, “C6”, “C7”, “C8”, “D5”, “D6”, “D7”, “D8”, “E5”, “E6”, “E7”, “E8”]

How could I do this program.I don’t know how can I changing the format.  
Please Anyone tell this answer fo this questions.

With Deep Regards,
