Finding Repetitive Character in String? in தமிழ் | Java | Explained | DinaTechy

Here's a explanation for Printing Repetitive characters in a String:
Logical Theory :
1. Start with an empty result set to store repetitive characters.
2. Iterate through each character in the string using for loop from the left to right.
3. For each character, compare it with the next character:
1. If they match, add the character to the result set (if not already present).
2. If they don't match, move to the next character.
4. Continue this process until you reach the end of the string.
5. The result set will contain all characters that appear consecutively at least once in the string.
6. Print or return the characters in the result set.
