Kata

It was difficult to understand the task just by looking at the text, but happy could solve it finally.

Can you please helt me to undaetnad the problem, 34, 32, 35 -> 35 -32 = 3, so will be come 50, 0, 3 and 49, 2, 2 and 51, 0, 0 so counting this will become 34 not 35, please help me to undertand the task is not very clear, Thank you!

Can you add this test chameleon([0,1,6], 1)? It complements the test added by AlexIsHappy with a case where one other color is "vastly" superior to desired one (explanation here).

Another suggestion for the description - wording is slightly misleading:

they can change their colors to a third one (i.e. when red and blue chameleons meet, they can both become green)

They both change their colors each time they meet. With this wording, you can think it is possible for them to keep their colors - which allows this incorrect case chameleons([0, 1, 2], 0).

Approved

Python, enjoyable. Had to explore and experiment my way to the logic behind the problem. Thanks for the Kata.

For Python, in Solution Setup:

1. Use snake case, not camelCase for variables (i.e. use use desired_color, not desiredColor).
2. Function name must be lowercase; capitalized names are reserved for classes by convention (i.e. chameleon(), not Chameleon()).

As there are already some solutions posted, if you change the function name they will be broken. To avoid this, you can add chameleon = Chameleon in test cases after you correct the second issue.

The test statements are wrong. For example

test.assert_equals(35, Chameleon([34, 32, 35], 0), "Wrong answer")

prints the following if -1 is returned:

Wrong answer: 35 should equal -1

To avoid this, please revert the test statements like this:

test.assert_equals(Chameleon([34, 32, 35], 0), 35, "Wrong answer")

Problem wording remains hard to understand and would benefit from editing.

Please clarify for me whether my interpretation of how chameleons change color is as intended. It is my understanding that if two chameleons meet, with one already the desired color, but the other some other color, then it is possible for both to emerge with the desired color. That is, if the desired color is red and a red chameleon meets a green chameleon, it is possible for the red chameleon to stay red, and for the green chameleon to turn red. Is this correct?

Nice Kata! Had quite a lot of fun!
