TUF+ Basic String - Finding the Largest Odd Number in a String | Java Solution
In this video, we walk through a Java solution to the problem of finding the largest odd number present in a string. The algorithm works by identifying the rightmost odd number from the string and removing any leading zeros to form the largest possible odd number.
We cover:
Understanding how to iterate through a string backward to identify odd digits
Handling leading zeros efficiently to get the correct result
Exploring edge cases (such as when no odd numbers exist in the string)
The provided Java code ensures an optimized solution, checking the string once and returning the largest odd number if it exists.
Code Breakdown:
We traverse the string from right to left.
Identify the first odd number from the right and break the loop.
Skip leading zeros to ensure the number is valid.
If no odd number is found, an empty string is returned. This solution demonstrates both logic and implementation in a clean, understandable manner.
