I did it by using a regular expression to find a node in the tree which is one level higher than a leaf node i.e. ( 0.5 ) is a leaf node ( 0.5 fluffy (1.0) (0.25) ) is the next simplest tree node. The key to identifying this tree is the ( () () ) pattern of brackets. I then used string

Anything to 7 decimal places is still within a precision of 10^-6, so the analysis is correct, and it won't be a typo. It is common to allow for much higher precision than asked for just in case you had an off- by-one error somewhere. On Sep 15, 9:01 pm, Matteo Landi landima...@gmail.com wrote:

Ok, i thought the checker would validate only results with that precision. My fault! On Tue, Sep 15, 2009 at 12:54 PM, TripleM stephenmerri...@gmail.com wrote: Anything to 7 decimal places is still within a precision of 10^-6, so the analysis is correct, and it won't be a typo. It is common

Google Code Jam allows standard scientific notations also, doesn't it? The grader is fairly sophisticated. You usually don't need to worry about decimal format unless it's the point of the problem. -Brian On Sep 15, 5:54 am, TripleM stephenmerri...@gmail.com wrote: Anything to 7 decimal

Relating to the contest analysis for Decision Tree: The hard part here was parsing the tree. The easiest way to do this is by using a technique called recursive descent. In (especially, but certainly not limited to) dynamic languages, there's an even easier technique, which is to use regular
