Interview question #3

I came out with another interview question to find out the candidate's visualizing power:

The object is chessboard--you know it has black and white squares.

How will you visualize the chessboard in terms of mathematical formula?
How will you visualize/depict the same in PHP code?

Thanks lawrence krubner for your comments. Actually, I'll be expecting just two keywords: Matrix and two dimensional array; that's all. I don't expect any brilliant answer:-)

Save American College, Madurai

This post was written in 2008 and outdated now. For update, please check Save American College, Madurai (Update 2011) Update (2011-01-16) : Save American College, Madurai (Update 2011) I'm highly privileged to have 3 degrees (B.Sc. (Spl. Physics), PGDCA and MCA) from The American College, Madurai, South India . Unlike other "commercial" colleges, American College has given room for poor students and uplifted them. And unlike other "elite" colleges who'd give seat only for "intellectuals", American College has produced geniuses. In the recent months, the saddening thing is that the college is under divide (Principal Vs. Bishop). Here is the email I sent to alumnae lately informing about the informations that I received about the developments: Update (2011-01-16) : Save American College, Madurai (Update 2011) All: I was thinking that the " Save American College " campaign was a FUD . But, when I tried to understand the problem through my...

Interview question #1

Since I have been asked to interview experienced PHP programmers, I was preparing few interview questions. I came to know, most of the people ask questions found in the Internet; most of them are like "What is the function used to connect MySQL DB in PHP". Personally, I don't like these types of questions; I'd thought the person must apply ideas what he was taught in colleges--finally I came out with one question: A product vendor has Quantity Vs. Price data like 1 -> Rs. 50 2 -> Rs. 95 3 -> Rs. 140 .... like upto 1 million data. He wants a system, which gives the price when the quantity is provided. For example, if you provide the quantity value as 2, then it should provide Rs. 95. How this system can be designed? As expected, all the people said about using database tables and quering on quantity. I have asked them to find out a system which doesn't use databases--provided the accuracy of the system may not be 100%--it may give at least 90% ac...

Interview question #2

This is related to PHP's array . An array has number of elements. All elements are integers and unique, which means there is no repetitive integers. (e.g.) $foo = array(7, 5, 9, 13, 2, 8); You have to sort the array, provided: You should scan the elements only once. You're not allowed to compare the elements when sorting. (i.e., you're not supposed to use any comparison operators) Sorted resultant array may not be the source array. How will you do that?
