  • Best way to get the highest sum from a Matrix (using Java but algorithm is the issue here)

    - by user294896
    Sorry I dont know the correct terminology to use but I have a 3x3 matrix like this 1 3 4 5 4 5 2 2 5 and I want get the highest score by picking a value from each row/column but I cant pick the same row or column more than once , so the answer in this case is 3 + 5 + 5 = 13 (row0,col1 + row1,col0 + row2,col2) 4 + 5 + 5 = 14 is not allowed because would have picked two values from col2 I'm using Java, and typically the matrix would be 15 by 15 in size. Is there a name for what Im trying to do, and whats the algorithm thanks Paul

    - by acidzombie24
    I dont understand how current can be null and last can be an object while last being a LINQ function. I thought last uses GetEnumerator and keeps going until current == null and returns the object. However as you can see the first GetEnumerator().Current is null and last somehow returns an object. How do linq Last() work? var.GetEnumerator().Current var.Last()

  • Should all the using directives for namespaces be inside the namespace?

    - by Sajeev SL
    Microsoft StyleCop provided a warning when the using directives for namespaces are provided outside of the namespace. Is this really required as my view on this is that using dircetives for namespaces is for providing a alias name for namespace and for removing the need for providing the namespace name when a class/interface is used. I dont think it will be used for loading the assembly.
