Sun Wukong Tang Seng rode Thon, followed by Sun Wukong. Sun Wukong ran fast, followed by a pig. Pig's nose is long, followed by a sand monk. Sand monk picked the ghost, followed by an old demon. The old demon real bad man cheated Tang Miao and Bajie. Tang Miao is really confused about the eight rings. It is impossible for a person to tell the story. I cannot tell it, thanks to Sun Wukong's bright eyes. Bright eyes shine with gold, and the Golden hoop is raised high. The golden
code are executed. A logical class of vulnerabilities, such as the above, often requires consideration of the risk of being bypassed and attacked in a particular business scenario. Incorporating security processes into the software development lifecycle is the best way to circumvent such vulnerabilities. Security Review ensures that business logic is not bypassed, the accuracy and security of user data flow is ensured before the code implements the functionality.Figure 2 2015 Application Vulner

Find the non-repeating integer in 250 million integers, and the memory is not sufficient to accommodate the 250 million integers.Scenario 1: The use of 2-bitmap (each number allocation 2bit,00 means that there is no, 01 means one time, 10 means multiple times, 11 meaningless), a total memory memory, and can be accepted. Then scan these 250 million integers to see the relative bitmap in the 01,01, and if the change is 00, the 10,10 remains the same. After the stroke is finis
statistics the TOP10 of this batch of data. This question is similar to the above question 3rd, heap sort: on each computer to find TOP10, can take 10 elements of the heap complete (TOP10 small, with the largest heap, TOP10 large, with the smallest heap). For example, for TOP10
1. The numbers marked are sometimes "not three", "not ten", and so on, all of which are in combination with 3 and 10. 2. Sometimes there are "more than ten contracts" and "more than 100 contracts", and so on, all of them are in the sum of 10 and 100. 3. Unknown: it is not described in the book, but it is estimated that it will not be too long within several rounds to dozens of rounds. 4. If the number * is in front of the name Table 1: all martial arts in The Romance of the Three Kingdoms (a
100 words.Solution: (1g=5000*200k, divide the file into 5,000 small files, 200k per file)1) Divide-and-conquer/hash mapping: In sequential read files, for each word X, take hash (x)%5000, and then follow that value to 5,000 small files (recorded as X0,x1,... x4999). So each file is about 200k, and each file holds a word with the same hash value. If one of the files exceeds the 1M size, you can continue to do so in a similar way until the size of the resulting small file is less than 1M.2) Hash

. Scenario 1: The use of 2-bitmap (each number allocation 2bit,00 indicates that there is no, 01 indicates that one time, 10 means many times, 11 meaningless), the total memory memory, but also acceptable. Then scan the 250 million integers to see the relative bitmap in the 01,01, and if it is 00 variable, the 10,10 remains unchanged. After the finished, look at the bitmap, the corresponding bit is 01 of the integer output. Scenario 2: You can also use a similar approach to the problem of small
) to get the most number of IPs. Specifically, it is: "The first is this day, and is to visit Baidu's log in the IP out to write to a large file." Note that the IP is 32-bit and has a maximum of 2^32 IP. The same can be used to map the method, such as module 1000, the entire large file mapping to 1000 small files, and then find out the frequency of each of the most frequent IP (can be used hash_map frequency statistics, and then find the largest number of frequencies) and the corresponding frequ

until the size of the resulting small file is less than 1M.2) Hash statistics: For each small file, the use of Trie tree/hash_map and other statistics in each file appear in the word and the corresponding frequency.3) Heap/merge sort: Take out the 100 words with the most frequent occurrences (you can use the smallest heap with 100 nodes) and deposit 100 words and corresponding frequencies into the file, so that you get 5,000 files. The last is the process of merging the 5,000 files (similar to
