Tip 1 : Regarding DSA preparation, I have a theory. 20 percent of the questions will be asked in 80 percent of the interview and 80 percent of the questions will be asked in 20 percent of the interviews. In short, some questions have a very high chance of coming up during the interviews and some have very low chance. We should focus more on the questions that have more chance of coming up in the interview. You can find these questions on Striver SDE Sheet, InterviewBit, Leetcode 100 most liked, Leetcode 100 most important.
Tip 2 : Try to find patterns in the questions. Group them according to a pattern for better understanding. Make notes in Excel, word or hand written and revise them.
Tip 3 : Try to solve the questions that have more chance of coming up in the interview with many different approaches.
Tip 1 : Make Sure that your resume is simple and also try to fit all the information in only one page.
Tip 2 : Have at least 2 projects with the latest technologies,Github link of projects should be provided
Check if any two intervals overlap among a given set of intervals. An interval is given in form of start and end time. Given a set of intervals, check if any two intervals overlap or not.

Implement the data structure which takes constant time for insertion, deletion and find operations.
Consider a pipe of length L. The pipe has N water droplets at N different positions within it. Each water droplet is moving towards the end of the pipe(x=L) at different rates.
When a water droplet mixes with another water droplet, it assumes the speed of the water droplet it is mixing with. Determine the no of droplets that come out of the end of the pipe.
You have been given an integer array/list(ARR) of size N which contains numbers from 0 to (N - 2). Each number is present at least once. That is, if N = 5, the array/list constitutes values ranging from 0 to 3 and among these, there is a single integer value that is present twice. You need to find and return that duplicate number present in the array.
