  • Ans. 

    The task is to compute the number of structurally unique BSTs that can be formed using an exact number of unique values.

    • Use dynamic programming to solve the problem efficiently.

    • The number of structurally unique BSTs can be calculated using Catalan numbers.

    • For N nodes, the number of structurally unique BSTs is given by the Nth Catalan number.

    • Example: For N=3, the number of structurally unique BSTs is 5.

Interview Preparation Tips

Professional and academic backgroundI applied for the job as SDE - 1 in BangaloreEligibility criteriaNASwiggy interview preparation:Topics to prepare for the interview - Dynamic Programming, Basic OOPS, Commonly Asked Algorithms (Kadane’s, Dutch National Flag and more), Data Structures (Heaps, Stack, Queues, HashMaps and more), Low Level Design (Machine Coding)Time required to prepare for the interview - 2 monthsInterview preparation tips for other job seekers

Tip 1 : Practice is they to success, every person will need a different path for preparation, the resources that you should use will depend upon your current expertise.
Tip 2 : For Machine Coding Rounds speed is key, you need to practice atleast 20 questions, Try to figure out techniques to common out code, code out your first question, and then spend good 2-3 hours in reducing no of lines and removing redundancy, try to note down methods you used to achieve less redundancy and for all the next questions you practice try to achieve that same quality from the beginning which will automatically increase your speed
Tip 3 : Do company wise preparation, look for interview experiences and try to map out commonly asked questions and categories of those questions and practice accordingly

Application resume tips for other job seekers

Tip 1 : If applying for any non FE role (or any role that does not require designing or creative skills) keep a minimalistic resume
Tip 2 : Ensure to add a summary at the top which mentions all the criterias HRs consider while short listing resumes (Experience, Degree and Branch, Languages you have experience in, City, Willingness to Relocate, Notice Period, If already on notice period mention your last working day)
