0-1 backpack problem: A thief in the theft of a shop, found that there are n items, the value of the article I item VI, heavy WI-lb, where VI and WI are integers. He hopes to take away the goods the more valuable the better, but his backpack can only be loaded W-pounds of Things, W is an integer. What kind of things should I take? This problem is called the 0-

In fact, I saw this in LINUX as early as I saw it. Later I also saw something similar in the MFC memory pool. I also wrote a similar small memory pool according to MFC, (MFC uses return this + 1) later, I saw a similar definition in Li xianjing's System Programmer growth plan, So I thought about it as a summary, the results showed that some cool people on the Internet had already summarized it very well, so it turned around. Thank you for your sharing

Given a group of items, each item has its own weight and value. within the defined total weight, how can we choose to make the total price of the item the highest. Solution: value density PI/wi (PI indicates the value of the item I, and WI indicates the weight of the item I) greedy algorithm. This selection criterion is: select the item with the highest PI/wi value from the remaining item. 0/1 the knapsac

Raid implementation:Raid: cheap redundant disk array, which turns several hard disks into a wholeLater, because it lost its original cheap purpose and became very expensive, it changed its nameIndependent redundant disk arrayAlthough we cannot implement raid on hardware, we can still implement raid because of our limited strength and we didn't buy those devices.Next we will look at how to implement soft RAID: 1. Implementation of soft RAID
