My solution is easier to understand. This was a lot like Fizzbuzz.

this is super slow...

My friend, we write solutions not tests. The TESTS round answers, not solutions. What are you talking about?

Very complex problem to figure out not only from the description, also the performance requirements are pretty high for being only a 6th kyu.

good

forbidden method

perfect examples of a simple problem solved with something that is really not worth trying to understand

Nice solution but mine better haha :)

clever

this is genius! thank you!

You have two chocolate bars. Each chocolate bar has portraits on it, but not necessarily in the same order. Your goal is to break the second chocolate bar as few times as possible in order to put the portraits in the same order as in the first bar. Each portrait is represented by a number from 1 to n.

For the example given:

first bar
|4|3|2|5|1|

second bar
|1|2|5|3|4|

There are three breaks you have to make in order to assemble the pieces in the correct order. One break between the 1 and 2, one between the 5 and 3, and one between the 3 and 4. That leaves you with the four pieces:

|1| + |2|5| + |3| + |4|

which can be rearranged to match the first bar:

|4| + |3| + |2|5| + |1|

I hope that makes sense.

clean

Really clever and fast solution.
