Asked about time complexity of algorithm, puzzles, DBMS, cutting edge technologies etc. What are indexes?
Given an array of integers ARR
of size N, consisting of 0s and 1s, you need to select a sub-array and flip its bits. Your task is to return the maximum count of 1s that can b...
Given an array of 0s and 1s, find the maximum count of 1s by flipping a sub-array at most once.
Iterate through the array and keep track of the maximum count of 1s obtained by flipping a sub-array.
Consider flipping a sub-array from index i to j and calculate the count of 1s in the resulting array.
Return the maximum count of 1s obtained by flipping a sub-array at most once.

Asked 1 standard algorithm
You are provided with a 2-dimensional matrix having N
rows and M
columns, containing only 1s (land) and 0s (water). Your goal is to determine the number of islands in t...
Count the number of islands in a 2D matrix of 1s and 0s.
Iterate through the matrix and perform depth-first search (DFS) to find connected 1s.
Mark visited cells to avoid redundant traversal.
Increment island count whenever a new island is encountered.
Tip 1 : prepare for competitive programming
Tip 2 : know about standard algorithm
Tip 3 : must be good with dbms
Tip 1 : must have projects, which you can explain to them
Tip 2 : have things on resume, that you are totally certain about.

Focusing on moderate level patterns
Object-Oriented Programming (OOP) is a programming paradigm based on objects that encapsulate data and behavior.
Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).
Inheritance: Mechanism to create a new class from an existing class, inheriting its properties (e.g., a 'Dog' class inheriting from an 'Animal' class).
Polymorphism: Ability to present the same interface for diffe...
