Episode :1 ! P: 1796. Second Largest Digit in a String
🎯 Second Largest Digit in a String | Java Coding Interview Question
In this video, we solve the popular coding interview problem:
"Given a string, find the second largest digit that appears in it."
You'll learn:
✅ How to extract digits from a string
✅ How to handle edge cases (like fewer than 2 digits)
✅ How to find the two largest digits efficiently
✅ Java coding explanation with comments and logic breakdown
This question is frequently asked in coding rounds and Java interviews, and we walk through the step-by-step logic to solve it using simple and clean Java code.
📌 Example
Input: "dfa12321afd"
Output: 2 (Digits are 1, 2, 3 → Second largest is 2)
