Let N be an arbitrary integer. What is the least number of weights that can be used on?
Q. Let N be an arbitrary integer. What is the least number of weights that can be used on a scale pan to weigh any integral number of pounds from 1 to N inclusive, if the weights can be placed in either of the scale pans?

A. What you need to figure out is how much "freedom" you have. First think of a simple application: If you only have to count in positive ways, how many stones do you need? Ignoring the other side of the scale, what would the solution be? Well, I want to be able to form all numbers from 1 to N, using some "system" -- what system would you use? How about a number system? For example, base 10 or base 7 or even base 2. The point is that if you have a number of pounds k (1 k N), you can write k in many ways, including sums of particular weights you might (or might not) have. If I had the weights {1,2,4,5} and I wanted to weight this against 7 pounds, I could either use: 7 = 5 + 2 7 = 4 + 2 + 1 So you see -- we don't want to be "re [cont.]

Things that tend to slow it down are when 802.11g, 802.11b, and 802.11n devices are connected to the same n-router device. … [cont.]

A. What I would do is go to the Pick-n-save and ask them what they put on their BLT sandwiches that makes them so good. Then follow what Sugar PIe wrote.
