BASIC ARRAY and STRING questions.
Tell me about the test automation tools you've used.
How would you design an automated testing framework for a Fleet Management System, considering the diverse types of vehicles and customization options available in Cox Automotive's projects? Discuss the key components and strategies you would implement
Basic introduction questions and experience
In first two rounds ds and algo questions were there. In 3rd round 1 Algo question was there and questions related to testing.

## 1. Count Valid Endpoint Combinations You are given - `S`: total number of servers - `C`: total number of clients - You need to **select exactly `K` endpoints** such that - At least `minS` of them are servers - At least 10 of them are clients. You are to compute how many valid combinations of endpoints you can select from the given servers and clients that satisfy all constraints. ### ✅Constraints: - `0 ≤ min S ≤ S ≤ 1000` - `0 ≤ min C ≤ C ≤ 1000` - `0 ≤ K ≤ S + C` - Use combinatorics to calculate combinations efficiently. - **Return the result modulo `10^9 + 7`**, as it can be very large. Input: S = 3, C = 1, minS = 1, minC = 0, K = 2 Output: 6 Input: S = 2, C = 3, minS = 1, minC = 1, K = 2 Output: 6 Input: S = 1, C = 3, minS = 2, minC = 1, K = 3 Output: 0 # 2. **Grey Level of Satellite Imagery** You are given a 2D grid of binary strings where each character is either `'0'` or `'1'`. This grid represents a black-and-white satellite image. Your task is to compute the **grey level value** of each cell based on the following rule: For each cell `(i, j)`in the grid: - Count the number of `'1'`s in **row `i`** and **column `j`.** - Count the number of `'0'`s in **row `i`** and **column `j`.** - The transformed value at `(i, j)` is ```markdown grey_level[i][j] = (ones_in_row[i] + ones_in_col[j]) - (zeros_in_row[i] + zeros_in_col[j]) ``` Return the **maximum value** among all the computed grey levels. Also, for debugging purposes, output the transformed grid.
