• CODE1 Spoj - cannot solve it

  - by VaioIsBorn

  I am trying to solve the problem Secret Code and it's obviously math problem. The full problem For those who are lazy to go and read, it's like this: a0,a1,a2,...,an - sequence of N numbers B - some number known to us X = a0 + a1*B + a2*(B^2) + a3*(B^3) + ... + an*(B^n) So if you are given B and X, you should find a0,a1,..an. I don't know how or where to start, because not even N is known, just X and B. Can you help me ?

• How do I add 2 years to a date in powerbuilder and account for the leap year correctly?

  - by Judy

  How do I add 2 years to a date in powerbuilder and account for the leap year correctly? We have a medical license application where the user would like the date to go expire two years. Current license date is 7/10/2010 and expire date should be 7/2/2012 I used relative date and added 729 if not a leap year and 730 if it was but that is messy. I wish the relativedate function took another parameter to so you could pass in number years.

• RenderPartial missing from Html Helper in ASP.NET MVC 2

  - by Guy

  I've just converted an application from MVC 1 to MVC 2 using the VS2010 wizard. Not found is the Html.RenderPartial which I have sprinkled around a number of views. I am guessing that this is something that I've done wrong because I see no mention of this as a breaking change in the white papers and docs. Everything I'm using is RTM/RTW and no beta or RC versions.
