I did, maybe I shouldn't be on codewars on Saturday at 12
If someone is willing to answer:

Q3. Are 2 + 1 and 1 + 2 considered 1 possiblity ?

Q1. Does negative numbers matter ? if so, then this is unsolvable (finitely), for example 2 can be summed with:

• -1 + 3
• -2 + 4
• -3 + 5
• -4 + 6
• etc until infinity..

Q2. Should I count 0 as a way to sum ? for example, the number 2 has these possible combinations:

• 0 + 2
• 1 + 1

About to forfeit this, passing the tests in ~300ms, when maximum allowed is 150ms

Anyone was able to submit with JavaScript recently ?
