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 tospend 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 toprovide an optimal algorithm or a program which separates zeroes and ones in aarray or somebody asks usto 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 confusedwhen we try to connect previous and next nodes whileinsertinga 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. It might so happen that, though we have around 8 to 10 years of software development experience, we still feel shaky and confused while literally tracing or debugging a recursive algorithm. The problem is though we know the solution, We will not be able to present it conveniently as we would have lost touch with the fundamentals of programming due to our day to day office routine, the workprocesses which are in place. Speaking of this course, here we have tried to cover majority of interview questions on algorithms and data structures in python along with the basics of data structures. We have literally traced/debugged most of the algorithms for several interview questions. We have explained the solutions for several interview questions for the following content: Stacks, Linked Lists, Trees, Arrays, Searching and Sorting. The course content is around 9 hours. Kindly check the preview for 30 mins. If you are interested, Kindly take up the course. The respectiveprograms are attached with the sessions. Kindly note that, We have focusedmore on explaining the optimal logic of the program rather then discussing the notations like Big Oof the algorithms. Kindly adjust the talkingspeed in accordance to your convenience (Please set the course narration speed on your convenience.). The concepts are presented in Neutral English. The below are the interview questions explained in the course:- write a program to implement stacks using lists- write a program to implement stacks using linked lists- write a program to balance symbols using stacks- write a program to convert an infix expression to postfix expression- write a program to evaluate a postfix expression- write a program to find out whether a string is a palindrome using stacks- write a program to reverse a given stack- write a program to insert a node at the beginning of a single link list- write a program to insert a node at the end of a single link list- write a program to insert a node after a particular position in a single link list- write a program to delete a node at the beginning of a single link list- write a program to delete a node at the end of the single link list- write a program to delete a node after a particular position in a single link list- write a program to search a node in a single link list- write a program to get the size of a single link list- write a program to insert a node at the beginning of a double link list- write a program to insert a node at the end of a double link list- write a program to insert a node after a particular position in a double link list- write a program to delete a node at the beginning of a double link list- write a program to delete a node at the end of the double link list- write a program to delete a node after a particular position in a double link list- write a program to find the nth node from the end of the single link list- write a program which suggests an alternative way to find the nth node from the end of the single link list- write a program which detects a loop in a single link list- write a program which finds the length of the loop in a single link list- write a program which finds the start node of a loop in a single link list- write a program which reverses the single link list using iteration- write a program which reverses the single link list using recursion- write a program w
