- Q1. Data structures questions
- Q2. Binary sort in array
- Ans.
Binary sort is a search algorithm that finds the position of a target value within a sorted array.
Binary sort works by repeatedly dividing the array in half and narrowing down the search range.
It is more efficient than linear search for large arrays.
Example: Sorting an array of strings alphabetically using binary sort.

The event loop is a mechanism in programming that allows for asynchronous execution of code.
The event loop is a key component in JavaScript's runtime environment, responsible for handling asynchronous operations.
It continuously checks the call stack for any pending tasks and executes them in a non-blocking manner.
The event loop ensures that the program remains responsive by allowing other code to run while waiting for ...

- Ans.
To find the fastest 3 horses out of a group with 5 horses racing at a time, we can use a tournament style approach.
Divide the horses into groups of 5 and race them against each other. This will give you the fastest horse in each group.
Take the winners from each group and race them against each other. The top 3 horses in this final race will be the fastest 3 overall.
Keep track of the results and compare the timings to d
- Q2. How do you debug the root cause of lag on a screen?

To debug lag on a screen, analyze code, check for memory leaks, optimize rendering, and use profiling tools.
Analyze code to identify any inefficient algorithms or operations causing lag.
Check for memory leaks that could be impacting performance.
Optimize rendering by reducing the number of draw calls, optimizing shaders, and minimizing overdraw.
Use profiling tools like Xcode Instruments or Android Profiler to identify p

- Q1. Given the frequency of traffic lights' states, can you determine if there will ever be an invalid state for the traffic signal, and what are the conditions that lead to an invalid state?
- Ans.
Yes, an invalid state can occur if the traffic lights are in conflicting states simultaneously.
An invalid state occurs when multiple traffic lights are showing conflicting signals, such as both red and green at the same time.
This can happen due to a malfunction in the traffic light system or human error in programming the lights.
For example, if a traffic light is stuck showing both red and green signals, it would be co
