Write a function to find the longest common prefix string amongst an array of strings. 写一个函数找到一个String类型的数组中的最长公共前缀。 If there is no common prefix, return an empty string "". 如果没有公共前缀,返回空字符串。 All given inputs are in lowercase letters a-z. 所有输入只...
Longest Common Prefix (LCP) array 继续上面的Suffix Array,字母排序后,我们一个个地用每一个元素同上一个元素比,标记相同前缀的字母个数,这个数字序列就是LCP 比如adc, adfgadc, 前缀ab是相同的,那就是2。 第一个元素没有“上一个”去比,所以LCP数组第1位永远是0?(是的,其实是undefined,但一般设0) ...

Space-Time Tradeoffs for Longest-Common-Prefix Array Computation The suffix array, a space efficient alternative to the suffix tree, is an important data structure for string processing, enabling efficient and often opti...

The longest-common-prefix (LCP) array is an adjunct to the suffix array that allows many string processing problems to be solved in optimal time and space. Its construction is a bottleneck in practice, taking almost as long as suffix array construction. In this paper, we describe algorithms ...
