In the record format, the caller and the called are separated by spaces. 13400001111 1008613500002222 1000013600003333 11413700004444 1258013711111111 1008613822222222 1258013922225555 1258018622220000 11418800000000 114 Now we need to create an inverted index to record all called numbers in the following format. The numbers are separated by |.

It is nothing more than getting the original webpage file, but the search engine's goal is to get an inverted index table. This is a helpless irony. 2. The number of existing web pages and the update speed cannot be achieved through diligence. Such as onlinedo
