Скачать или смотреть DSA Question 08 || Sum of even digits from a given number || Placement Interview Questions

📖 Description:
In this video, we write a Java program to calculate the sum of even digits of a number using recursion. The program takes a number, breaks it into digits recursively, checks if the digit is even, and then adds it to the total sum.

You will learn:
✅ How recursion works in digit-based problems
✅ Dry run of the code with example input
✅ Time Complexity: O(log n) (since the number of recursive calls depends on digits)
✅ Space Complexity: O(log n) (stack space due to recursion)



🔎 Example Run:
Input: 123456
Even digits → 2, 4, 6
Sum = 12
