Here’s an example of how the same problem might be approached differently in Software Engineering and Computer Science:

Problem: Implement a function to find the nth Fibonacci number

Software Engineering Approach:
public class FibonacciCalculator {
    public static long calculateFibonacci(int n) {
        if (n < 0) {
            throw new IllegalArgumentException("n must be non-negative");
        }
        if (n <= 1) {
            return n;
        }
        long prev = 0, curr = 1;
        for (int i = 2; i <= n; i++) {
            long next = prev + curr;
            prev = curr;
            curr = next;
        }
        return curr;
    }
}

This implementation focuses on readability, error handling, and efficient memory usage.

Computer Science Approach:
import java.util.HashMap;
import java.util.Map;

public class FibonacciCalculator {
    private static Map<Integer, Long> memo = new HashMap<>();

    public static long calculateFibonacci(int n) {
        if (n < 0) {
            throw new IllegalArgumentException("n must be non-negative");
        }
        if (n <= 1) {
            return n;
        }
        if (memo.containsKey(n)) {
            return memo.get(n);
        }
        long result = calculateFibonacci(n - 1) + calculateFibonacci(n - 2);
        memo.put(n, result);
        return result;
    }
}

This implementation uses memoization to optimize the recursive solution, demonstrating a focus on algorithmic efficiency and dynamic programming techniques.
