After analysis, the time complexity of hash search is O (1). Similarly, trie search time complexity is O (1 ). then the time complexity of searching the entire word is O (1 ).3. Rule-Based Word Segmentation Algorithms:
This word segmentation system is also a dictionary-based Improved maximum matching algorithm.
There are many word segmentation algorithms. Common algorithms are forward and reverse maximum matching. However, these two algorithms do not provide good support for sentences
segmentation system uses mechanical word segmentation as a preliminary scoring method, and uses other language information to further improve the accuracy of segmentation.
Let's take a look at two Chinese sentences:
1) Speech by Mayor Changchun during the Spring Festival
2) Changchun pharmacy
Assume that the Lexicon contains the following words: "Changchun", "Changchun", "Mayor", "Spring Festival", "speech", "Spring Festival medicine", and "

simply using reverse maximum matching is 1/245. But this precision is far from satisfying the actual need. The actual use of the word segmentation system, is the mechanical participle as a primary means, but also by using a variety of other language information to further improve the accuracy of segmentation.

right to buy the drug, the price of regional distributors, the price of the provincial agency, the PR for entering hospitals and drug stores cost. Although agents generally make public claims that the markup rate does not exceed 15%, it is not difficult to see from the above example of an iron supplementation price increase that the markup rate is much higher than the national regulations. To this end, the agent will take measures such as raising the ex-factory price to reduce the Markup Rate

the new master. Slave is selected based on a priority to determine the DNS situation. The same priority is obtained through the runid sorting. However, the priority setting has not yet been implemented, so you can directly obtain the runid sorting to get slave 1.
Then, the command slaveof no one is sent to cancel the slave status of slave 1 and convert it to the master. When the other sentinel observes that the slave becomes the master, it will know that the error handling routine is started. S
There are three different buildings in the gameplay of the gang: The Vault, the pharmacy, and the Chamber. Different buildings bring different help to the players. To upgrade a gang, you must first upgrade all three buildings to level 2.Vault upgrade:The role of the vault is to allocate half-shot dividends.
