Problem Solving Challenge

In this section, you'll find a unique challenge designed to test your problem-solving skills. Can you think like a programmer and solve it?

Detecting Consecutive Tiny Words

Description:

There’s a common guideline in writing: avoid sequences of tiny words. This means that if a sentence contains three or more consecutive two-letter words, it's considered to have too many tiny words.

Your task is to write a JavaScript function that checks if a given sentence contains a sequence of three or more consecutive two-letter words.

Function Signature:

function hasTinyWordChunk(sentence) {
  // write your logic below this line
  return false
}

// Test cases
console.log(hasTinyWordChunk('Please go to the store and do it quickly.')) // false
console.log(hasTinyWordChunk('It is so great to finally meet you in person.')) // true
console.log(hasTinyWordChunk('I am so glad that you can go now and enjoy the event.')) // false
console.log(hasTinyWordChunk('He is at it by himself, trying to fix up the car.')) // true

Example Sentences:

• "Please go to the store and do it quickly."

• "It is so great to finally meet you in person."

• "I am so glad that you can go now and enjoy the event."

• "He is at it by himself, trying to fix up the car."

Expected Output:

1. false (no three consecutive two-letter words)

2. true (because "It is so" has three consecutive two-letter words)

3. false (no three consecutive two-letter words)

4. true (because "is at it" has three consecutive two-letter words)

A) true, ['red', 'blue', 'green']

B) true, ['red', 'purple', 'green']

C) false, ['red', 'purple', 'green']

D) false, ['red', 'blue', 'green']
