<ul data-eligibleForWebStory="true"><li>LeetCode 2138 presents an easy string manipulation problem that involves dividing a string into groups of a specified size k.</li><li>The task includes dividing the string into groups of size k and padding the last group if it has fewer than k characters with a specified fill character.</li><li>The C++ solution involves iterating through the string and adding substrings of size k to a list while padding the last group if necessary.</li><li>Key notes include checking for remaining characters, padding using the fill character, and the time complexity being O(n) where n is the length of the string.</li><li>The JavaScript solution utilizes slicing to grab groups and repeats the fill character if padding is required.</li><li>The Python code demonstrates a similar approach using string slicing and handling edge cases with padding if the chunk size is less than k.</li><li>Overall, the problem focuses on string slicing, iteration, and padding for edge cases, making it a practical exercise for understanding these concepts.</li></ul>
