我正在阅读 Accelerated C++。我不明白练习 5-1:
Design and implement a program to produce a permuted index from the following input. A permuted index is one in which each phrase is indexed by every word in the phrase.
The quick brown fox jumped over the fence The quick brown fox jumped over the fence jumped over the fence The quick brown fox jumped over the fence The quick brown fox
那个解释对我来说不是很清楚。什么是置换索引?
最佳答案
The term permuted index is another name for a KWIC index, referring to the fact that it indexes all cyclic permutations of the headings. Books composed of many short sections with their own descriptive headings, most notably collections of manual pages, often ended with a permuted index section, allowing the reader to easily find a section by any word from its heading. This practice is no longer common.
