2788. Split Strings by Separator

Easy

Array String

Problem Explanation

Explanation:

To solve this problem, we need to iterate through each word in the array and split it based on the given separator character. We can achieve this by using the split function provided by most programming languages. After splitting each word, we need to filter out any empty strings in the result and store the non-empty strings in a new array. Finally, we return this new array as the output.

We iterate through each word in the input array.
For each word, we split it using the separator character.
We filter out any empty strings from the split result.
We store the non-empty strings in a new array.
We return this new array as the output.

Solution Code

import java.util.ArrayList;
import java.util.List;

class Solution {
    public List<String> splitStringsBySeparator(String[] words, char separator) {
        List<String> result = new ArrayList<>();
        for (String word : words) {
            String[] splitWords = word.split(String.valueOf(separator));
            for (String splitWord : splitWords) {
                if (!splitWord.isEmpty()) {
                    result.add(splitWord);
                }
            }
        }
        return result;
    }
}
