Case study
In a case study interview, you'll be given a real-world business problem and asked to analyze the situation and come up with solutions or recommendations. The goal is to evaluate your problem-solving, analytical thinking, and decision-making abilities.

**Coding tests** are commonly used in technical interviews to evaluate your programming skills. These tests usually involve solving algorithmic problems, debugging code, or writing efficient code to handle certain tasks. Here are the general types of coding tests you might encounter:

### 1. **Algorithm and Data Structure Questions:**
These focus on your ability to use algorithms and data structures to solve problems efficiently.
- **Sorting and Searching**
Example: Implement a sorting algorithm like QuickSort or MergeSort, or write a binary search function.
- **Linked Lists**
Example: Reverse a linked list or detect a cycle in a linked list.
- **Trees and Graphs**
Example: Find the height of a binary tree, or perform a breadth-first search (BFS) or depth-first search (DFS) on a graph.
- **Dynamic Programming**
Example: Solve problems like the Fibonacci sequence, the knapsack problem, or longest common subsequence.
- **Recursion**
Example: Write a function that calculates factorials or solves the Towers of Hanoi problem.

### 2. **String Manipulation:**
These problems test your ability to handle and manipulate strings efficiently.
- Example: Write a function to check if a string is a palindrome, or find the longest substring without repeating characters.

### 3. **Mathematical Problems:**
These involve solving problems with mathematical concepts.
- Example: Check if a number is prime, or find the greatest common divisor (GCD) of two numbers.

### 4. **Array and Matrix Problems:**
These involve operations and algorithms on arrays or matrices.
- Example: Rotate a matrix, find the maximum sum subarray (Kadane’s algorithm), or merge two sorted arrays.

### 5. **Problem Solving with Constraints:**
In some cases, you may be given a problem where you need to optimize for time or space complexity.
- Example: Write an algorithm that finds the shortest path in a maze with obstacles, and ensure that it runs in O(n log n) time.

### 6. **Debugging:**
In some coding tests, you might be asked to debug a given piece of code that’s producing errors or incorrect output.

### 7. **Object-Oriented Design:**
These questions test your ability to design systems and classes using object-oriented principles.
- Example: Design a class to represent a library system, or implement a parking lot with multiple types of vehicles.

---

### Tips for Coding Tests:

1. **Understand the Problem:**
- Read the problem statement carefully before jumping into writing code.
- Clarify the input, output, and constraints with the interviewer (if needed).

2. **Plan Your Approach:**
- Before writing code, think about the algorithm you’ll use and the time/space complexity.
- Break down the problem into smaller steps and outline your solution.

3. **Write Clean, Efficient Code:**
- Focus on writing readable and efficient code.
- Optimize your solution to handle edge cases and large input sizes.

4. **Test Your Solution:**
- Test your code with sample inputs, including edge cases (empty input, large numbers, etc.).

5. **Communicate Your Thought Process:**
- As you write your code, explain your approach to the interviewer. This shows your problem-solving process.

### Example Coding Problem:

**Problem:**
Write a function to find the "Nth" Fibonacci number.

**Solution:**
```python
def fibonacci(n):
if n <= 1:
return n
a, b = 0, 1
for i in range(2, n+1):
a, b = b, a + b
return b
```

**Explanation:**
- The Fibonacci sequence starts with 0 and 1, and each subsequent number is the sum of the two preceding ones.
- We use an iterative approach to calculate the Fibonacci number at the nth position.

### Practice Platforms:
To prepare for coding tests, you can practice on the following platforms:
- **LeetCode**
- **HackerRank**
- **CodeSignal**
- **Codewars**
- **Exercism**

These platforms provide a wide variety of problems to improve your coding skills and familiarize yourself with common interview questions.

An **assignment** in the context of a job or academic setting is typically a task or project that you're asked to complete as part of your evaluation.
