Write in front In today's Internet industry, especially in the current distributed and micro service development environment, in order to improve search efficiency and search accuracy, a large number of NoSQL databases such as Redis and Memcached will be used, as well as a large number of full-text retrieval services such as Solr and Elasti ...

School of magic Title Description: Yako likes to collect visible characters without spaces (ASCII code is 33 ~ 126). In her eyes, the value of a character is its ASCII code size, such as the value of 'a' is 97. So far, she has collected n visible characters excluding spaces, and the ith character is Si. But she wanted to maximize the val ...
