• Good Hash Function for Strings

  - by Leif Andersen

  I'm trying to think up a good hash function for strings. And I was thinking it might be a good idea to sum up the unicode values for the first five characters in the string (assuming it has five, otherwise stop where it ends). Would that be a good idea, or is it a bad one? I am doing this in Java, but I wouldn't imagine that would make much of a difference.

• C++ Array Initialization in Function Call or Constructor Call

  - by david

  This question is related to the post here. Is it possible to initialize an array in a function call or constructor call? For example, class foo's constructor wants an array of size 3, so I want to call foo( { 0, 0, 0 } ). I've tried this, and it does not work. I'd like to be able to initialize objects of type foo in other objects' constructor initialization lists, or initialize foo's without first creating a separate array. Is this possible?

• Define polynomial function

  - by user1822707

  How can I define a function - say, def polyToString(poly) - to return a string containing the polynomial poly in standard form? For example: the polynomial represented by [-1, 2, -3, 4, -5] would be returned as: "-5x**4 + 4x**3 -3x**2 + 2x**1 - 1x**0" def polyToString(poly): standard_form='' n=len(poly) - 1 while n >=0: if poly[n]>=0: if n==len(poly)-1: standard_form= standard_form + ' '+ str(poly[n]) + 'x**%d'%n else: standard_form= standard_form + ' + '+str(poly[n]) + 'x**%d'%n else: standard_form= standard_form + ' - ' + str(abs(poly[n])) + 'x**' + str(n) n=n-1 return standard_form
