Autonomy Zantaz Interview Question
System AdministratorsYou guys are on the right track, but let's put it this way. Lets say it was a square. The sides are each "x" length, so the diagonal of the square is x * sqrt 2. Therefore, positioned correctly, the cover would be able to fall in, since there is a way for the opening to be greater than the length of one of the sides. With a circle, it's always diameter D and it can't fall in.
Perfect ans..i gave the same ans in one of my interview, when I was asked this stupid que. :D
Man holes covers are heavy... so if they are circular, we can roll them.
Also, for a man to enter a man hole, the smallest area needed is a circle.
Also, the cover wont fall into the hole if it is circular. if it was square, there is a chance of falling.
"Also, the cover wont fall into the hole if it is circular. if it was square, there is a chance of falling."
I do not understand the logic behind this statement. How does the shape matter if the manhole is built such that it holds the cover appropriately? Are you bringing in some theory of gravity and surface area?
if the man cover is not having the shape of a circle, then there is a chance that the hole won't be covered properly every time... but if it is having the shape of a circle.. then no matter how you place it it will close the hole perfectly..
