Fractals and me


I can keep writing on and on about fractals. I can keep talking on and on about fractals.

Such is my interest in fractals. Knowing about fractals and understanding them gave me a very assuring thought that most of the things that we see around are structurally same, the large is made of many tinies, where each of the tiny is identically resembling the large.

Its like saying that Rahman is made of millions and trillions of tiny cells, where each of the cell is structurally same or unique to Rahman!

I may be wrong in putting so, but i might be right as well.

I clearly feel that when we observe an object from atomic level to the visible comprehensible level, somewhere that object represents a fractal.

Once something fits into a fractal, it is perhaps fitting into a mathematical equation. Could be at DNA level, could be at molecular level, could be at organ level, could even be at organism level, fractals are evidently visible.

Physically seeing fractals is one thing, my belief, is that fractals are even there in the way we think. Yes, in inanimate things like thoughts, emotions, every tangible and intangible things around us do have a manifestation of fractals.

Every small emotion we have is part of a bigger emotion and every bigger emotion we keep is built up from small emotions identically same but maybe in smaller intensites.

This is a way of me trying to tackle problems that seem to be very big. At some level any huge problem is not huge but fractally built of tiny problems. And if I could break down that huge problem into many smaller problems, and in turn each smaller problem further into tiny problem, its easy to tackle down. And the solution you come up for such tiny problem, can be amplified to fix the smaller problem and in turn the huge problem.

First Amazon Telephonic Interview

I had this opportunity to have interview with Amazon with the help of my friends, who referred me for SDE position.

Immediately after my friends’ reply that he has given my resume with a recruiter and I may get a call from recruiter, I got a call from some person with my interview schedule.

With a lapse of half an hour after schedule, my first interview started.

The interviewer was humble supportive one. After introductions, he straight away asked me questions one after another.

They were:

  1. Implement a stack with push, pull and findmin in O(1) time.
  2. There is an array of positive random integers. All the elements are repeated twice except for one. Find that element.
  3. Wap to stitch all the leaf nodes of a binary tree together. After stitching, the tree becomes a graph, and the stitched elements be stored in a list. Return the head node of the list.

I could quickly answer the first two ones, but had trouble writing working code for the third one. After several minutes passed. And my code messed up, I was asked to leave it. And the phone interview concluded.

With a gap of one hour, I had a second telephonic interview.

This time I was asked only two questions.

They were :

  1. Wap. There is a circular singly linked list, All elements are in ascending order. Insert a given number at its correct place in the list. The number is a random one.
  2.  There is a stair case, at each step, a person can either take two steps or one step. What is the total number of steps?

With the guilt of being unable to do the previous interview coding properly, here, I directly wrote the implementation part of the linked list, without even checking my implementation was a mere singly linked list and not a circular one. Also, missed the syntax errors like a semi-colon(;) at end of struct declaration, etc. And after correcting me for those mistakes, or rather blunders, the interviewer moved onto second question, and I was trying to solve it mathematically and come out with a polynomial expression, while the interviewer intended me to derive a recursive function out of it. After failing with it, the interviewer advised me to follow codechef, topcoder kind of websites and to do more practice.

Hours after interview, I received a mail saying, I am not offered a job/no call for further interview.

I can reapply in 6 months.

Waiting for my second turn now, and practicing for it.

movie buff part of me

i watch movies very selectively, (not rarely for sure, after all its the cheapest means of entertainment according to my III grade social text book — the authors didnt go for PVR or Prasad’s for sure 😉 ) and if i watch a movie, then the movie is a previleged one.

I watch movies that emphasise on India Patriotism, Indian Culture and Telugu culture.

I hate action movies and filthy ones without head & tail — the present trend telugu movies.

I need to write more and more. so this entry of mine will have many editings in future.
