ReplyDeleteDear "Interview Questions",
ReplyDeleteI appreciate your taking time to comment, and you are absolutely correct; that would be the optimum way to get it.
However as you would notice, most of my posts are rather stand-alone quick tricks to get the job done with minimal code, and not necessarily optimized or scaled for large scale consumption. Some times we just need a quick way to get stupid things done :-)
Please do keep visiting, and share your thoughts like above.
Cheers!
