One of my friends who works in a big MNC recently asked me that if there is any way to check if the String is Palindrome or not. The palindrome is a word, phrase, or sequence that reads the same backward as forward. For example A man, a plan, a canal – Panama! is palindrome so as Was it a car or a cat I saw?
My first reaction was to him was why does this kind of functionality. His answer was they have requirement in their business application where they are building captcha and they may display the image in mirror image as well as a part of challenge code and he can’t have any word which is palindrome as an option. For this he wanted to write a script which will go letter by letter and match them. If they are same, he will not use the word for captcha.
Here is a very interesting question asked on the blog by Karthik. I really liked the question and I would like to discuss this here about SSMS doe snot Print NULL values.Â
Learning any technology is easy when we have good documentation and sample database to play along with. When I have to learn any new technology, my first action is to install the trial software and look for sample database next. Once I get sample database, I try to find a video tutorial about the technology and continue to learn onwards. Let’s see PowerPivot for Excel 2010 and PowerPivot in Excel 2013 Samples here.
