HDU 4334Test instructionsGive a collection of five numbers, and ask if you can take a number from each set so that the sum of five numbers is 0.Ideas:The collection size is 200, and the complexity of the direct enumeration is 200^5, which must time out.The upper limit of the direct enumeration is 3 layers, we can enumerate the remaining two sets of each element can be composed of elements and hash, so that we can quickly determine the enumeration of the three sets of elements and in the remainin

Typically, database firewalls and data-path encryption products can solve such problems. Now access to data more ways, then in the system left the backdoor and the way to steal data has become more, the value of user data has increased, so now the frequency of data leakage is also an inevitable phenomenon, the database security is gradually increased maintenance awarene

After the boot, first load the bios program, obtain the boot sequence, and find the first boot device. Then, read the mbr sector information of the first startup device. Normally, the Mbr displays the grub (GRand UnifiedBootloader is a program

Document directory Why? Code is a by-product The most basic fact of software development is that we must write code, but the biggest misunderstanding of this fact is that our job is to write code. As a software programmer, I have been confused by this idea for the first few years. Writing code is a very strong task and a super power, we like this feeling of creating and achieving things. However, after many years, I finally realized that this was not the case. The truth is: the programmer
