Read a buffer of unknown size (Console input)

Hi. I'm a little behind in my X86 Asm class, and the book is making me want to shoot myself in the face. The examples in the book are insufficient and, honestly, very frustrating because of their massive dependencies upon the author's link library, which I hate. I wanted to learn ASM, not how to call his freaking library, which calls mor...

Set combination question

Got this as an homework assignment and not really sure where to start! Given the set {1,2,3,4}, you can form six combinations of length two from that set, viz: {1,2},{1,3},{1,4},{2,3},{2,4},{3,4} If I was to choose one of the combinations, ({1,2} for example), how can I tell how many of the others are not disjoint to it? In this cas...

What's a good algorithm to distribute points between weighted items?

I have 100 points to dole out to a set of items. Each item must receive a proportional number of points relative to others (a weight). Some items may have a weight of 0, but they must receive some points. I tried to do it by giving each item 5 points, then doling out the remaining points proportionally, but when I have 21 items, the a...
