Python: Solved Interview Ques on Algorithms, Data Structures

Welcome to the course "Python: Solved Interview Questions on Algorithms and Data structures". This course is from a software engineer who has managed to crack interviews in around 16 software companies. Sometimes, life gives us no time to prepare, There are emergency times where in we have to buck up our guts and start bringing the situations under our control rather then being in the control of the situation.

At the end of the day, All leave this earth empty handed. But given a situation, we should live up or fight up in such a way that the whole action sequence should make us proud and be giving us goosebumps when we think about it right after 10 years. We would have observed the fact that though most of us are developers, only few would get a chance to work on certain advanced programming stuff like Data Structures, Linked Lists, Trees.

The rest of us get to spend time in Bug fixing, resolving Maintenance issues during our work hours. Though this work doesn't help us much in improving our learning curve, it certainly feeds us and our families. So, Keeping this in mind, at the work place, We don't have any option but to work honestly.

But, the real trouble starts when we start attending interviews and suddenly somebody asks us to provide an optimal algorithm or a program which separates zeroes and ones in a array or somebody asks us to provide an efficient algorithm which will get the diameter of a tree. There can also occur a situation where in we think twice or get confused when we try to connect previous and next nodes while inserting a node between two nodes in a single or double link list. Most of the times, the interviewer feels happy if we give him/her an optimal solution for a problem.
