Software Engineer intern+PPO

Step 1: I carefully read through the provided class structure, which included a base Shape class and derived classes like Circle, Rectangle, and Triangle, with function signatures already defined.
Step 2: I identified the functions that needed to be implemented, such as getArea(), getPerimeter(), and displayInfo(), in each derived class.
Step 3: I implemented the logic for each function using the correct mathematical formulas based on the shape's properties.
Step 4: I ensured that each derived class properly overrode the base class methods, demonstrating the use of inheritance and polymorphism.
Step 5: Finally, I tested the implementation by creating different shape objects and calling their methods to verify correct outputs and behavior.

This was an easy-level problem where I had to count how many times each number appeared in a list. I used a map because it made it easy to store each number as a key and keep track of how many times it occurred. The logic was simple and direct.

Step 1: I listened to the problem carefully as explained by the interviewer.
Step 2: I decided to use a map to store each number and its count.
Step 3: I went through the list one number at a time.
Step 4: For each number, I checked if it was already in the map. If yes, I increased its count by 1. If not, I added it to the map with a count of 1.
Step 5: After finishing the list, the map had all numbers with their frequencies, which I then displayed as the final result.
