I took greater one hour to resolve this kata but still can't pass by. Maybe my mind is bad with MATH.

If there is 100 languages, you will have 100 if command, are u serious?

Maybe my level is really at 7 kyu :((

I agree with you, but the level of kata is not determined by the author.
It depends on the average level of voting and the moderator's consideration ;-)

I don't know how I'm bad at algorithm but I think this kata should be 6 kyu level... :((

What if we have to print 100 lines ? :|

Nice story about Basic Encryption algorithm. I've finished this with for loop and some condition commands. Regex was more advanced!

Personally, I like your approach method what based on something real-world!

Keep going. Thanks a lot!

OK, fixed. Thanks for your feedback ;-)

A spelling error:

We can see, str.index("e") equals str.lastIndexOf("e"), because there is only one "e" in str

Should:

str.indexOf("e")

^^

Yep, my mistake. I didn't read description carefully.

I've finished this kata. Thanks for your support! ;)

Yes, next time i can travel to myjinxin town:-)!

I'm sure that you havn't completely read my description ;-)
Do you know which one is the fruit? Do you cut "Obama" to "Oba" and "ma"? Obama is crying...
DO you read these text in description?

In order to make clear what is the fruit, you may need a list fruitsName(fruits_name in Ruby). It's a preloaded variable, you can use it directly.

我也？me too? Your Chinese is very well ;-)

我也;-)
