# --description--
|
|
|
|
Today's challenge is inspired by the release of ChatGPT on November 30, 2022.
|
|
|
|
Given a string of one or more sentences, determine if it was likely generated by AI using the following rules:
|
|
|
|
- It contains two or more dashes (`-`).
|
|
- It contains two or more sets of parenthesis (`()`). Text can be within the parenthesis.
|
|
- It contains three or more words with 7 or more letters.
|
|
|
|
- Words are separated by a single space and only consist of letters (`A-Z`). Don't include punctuation or other non-letters as part of a word.
|
|
|
|
If the given sentence meets any of the rules above, return `"AI"`, otherwise, return `"Human"`.
|
|
|
|
# --hints--
|
|
|
|
`detect_ai("The quick brown fox jumped over the lazy dog.")` should return `"Human"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(detect_ai("The quick brown fox jumped over the lazy dog."), "Human")`)
|
|
}})
|
|
```
|
|
|
|
`detect_ai("The hypersonic brown fox - jumped (over) the lazy dog.")` should return `"Human"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(detect_ai("The hypersonic brown fox - jumped (over) the lazy dog."), "Human")`)
|
|
}})
|
|
```
|
|
|
|
`detect_ai("Yes - you're right! I made a mistake there - let me try again.")` should return `"AI"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(detect_ai("Yes - you're right! I made a mistake there - let me try again."), "AI")`)
|
|
}})
|
|
```
|
|
|
|
`detect_ai("The extraordinary students were studying vivaciously.")` should return `"AI"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(detect_ai("The extraordinary students were studying vivaciously."), "AI")`)
|
|
}})
|
|
```
|
|
|
|
`detect_ai("The (excited) student was (coding) in the library.")` should return `"AI"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(detect_ai("The (excited) student was (coding) in the library."), "AI")`)
|
|
}})
|

```
