00:00 - Introduction to dataset and Question
03:55 - Approach 1: Brute Force Method
05:40 - Approach 2: Using enumerate and truncate
07:25 - Approach 3: Simple split, slice and join
09:30 - Conclusion

You are given a sentence s and an integer k. You want to truncate s such that it contains only the first k words. Return s after truncating it.

A sentence is a list of words that are separated by a single space with no leading or trailing spaces. Each of the words consists of only uppercase and lowercase English letters (no punctuation).

** Approach 1: Brute Force Method **
1. Split the sentence into words
2. Iterate through the words and collect the first k words
3. Join the collected words to form the truncated sentence

** Approach 2: Using enumerate and truncate **
1. Split the sentence into words ***
1. Use enumerate to iterate through the words with their indices
2. Collect the first k words and join them to form the truncated sentence

** Approach 3: Simple split, slice, and join **
1. Split the sentence into words ***
2. Use slicing to select the first k words
3. Join the selected words to form the truncated sentence
