Wrap Text to a Fixed Width

Hard ⏱ 18 min 25% acceptance ★★★★☆ 4.3

Write a function wrap_text(text, width) that wraps a single-line string text into multiple lines, each at most width characters long, breaking only at spaces (never splitting a word), and returns the result as one string with lines joined by \n. Assume no single word exceeds width characters.

Examples

Example 1

Input

wrap_text("the quick brown fox jumps", 10)

Output

'the quick\nbrown fox\njumps'

Explanation

Words are packed greedily without exceeding 10 characters per line.

Example 2

Input

wrap_text("hi", 10)

Output

'hi'

Explanation

Fits on one line.

Constraints

text has one or more space-separated words; width is a positive int at least as large as the longest word.

Hints

Hint 1

Iterate words, tracking the current line; when adding the next word would exceed width, start a new line.

Hint 2

Watch the "would this line + word (plus a space) exceed width" check carefully for the first word on a line.
