Easier than the classic version since you skip the padding logic entirely.
Clarify that 'greedily' means adding words to the current line as long as the total length including single spaces stays within the width limit. Then implement a single-pass solution using a pointer to track the current word and build each line by accumulating words until the next word would exceed the limit. Return the list of lines without any padding or justification.
Pro tip: Explicitly state that you will not add trailing spaces or justify lines, and mention that you'll handle edge cases like a single word longer than the width by placing it on its own line. This shows attention to detail and avoids over-engineering.
Confirm that lines should not be padded or justified, and that words are separated by single spaces. Ask about edge cases: empty array, single word longer than width, and whether words can be split.
Explain that you will start a new line with the first word, then keep adding the next word if the current line length plus one space plus the next word's length is <= maxWidth. Otherwise, finalize the line and start a new one.
Use an index to iterate through the words. For each line, track the current length and a list of words. Add words until the limit is reached, then append the joined line to the result and continue.
If a word is longer than maxWidth, place it alone on a line (since it cannot fit with others). Ensure the last line is added after the loop ends.
State that the time complexity is O(n) where n is the total number of characters, and space is O(n) for the output. Walk through a small example to verify correctness.
