Updated Node to v12

• Node 12 should be enabled (Refer this and this for more info)

input 7 has only one digit. so, 7**(1) is the way to look at it.
for example 456 is the input then execution looks like 43 +53 +6**3 because it has 3 digits

There are two missing images in the description of the problem. I believe that they are to images on wikipedia.

Yes, this is the JavaScript version.

Please specify language (I suspect JS), and mark it as an issue.

Thanks. I hope u rated it.

5 probably wouldn't be unreasonable. But I think it also passes for a "tough 6". Ratings are a little subjective here ;)

Approved

This challenge is far more difficult than most of the 6 kyu, I've come across. Not sure what it should be, but certainly not level 6.

There is a discrepency between the intructions and the actual tests. Numbers with a decimal part should return "The number has a decimal part. No Results", but instead you test for "The number has a decimal part."

The exponent is based on the number of digits the number is composed of. So 7, being composed of 1 digit, would be 7^1, which is 7.

Thank you. Added random tests. I would welcome any comments about my tests and how to make them better. /fixed.

Thanks for the feedback. /fixed
