DISUBSTR - Distinct Substrings |
Given a string, we need to find the total number of its distinct substrings.
Input
T- number of test cases. T<=20;
Each test case consists of one string, whose length is <= 1000
Output
For each test case output one number saying the number of distinct substrings.
Example
Sample Input:
2
CCCCC
ABABA
Sample Output:
5
9
Explanation for the testcase with string ABABA:
len=1 : A,B
len=2 : AB,BA
len=3 : ABA,BAB
len=4 : ABAB,BABA
len=5 : ABABA
Thus, total number of distinct substrings is 9.

If you write an O(n) algorithm of suffix array(such as "DC3" or "SA-IS") , you just need to calculate the LCP of every two suffix which rank is nearby,then you just use sigma(1~lenth(string)) minus sigma(i=1 to lenth(string))height i; the answer will be calculated. The whole algorithm will be O(n). |

"SUBST1 - New Distinct Substrings" - NOT passed in (NLOG^2N) string length large "DISUBSTR - Distinct Substrings" - passed in (NLOG^2N) small string length |

AAA is also a possible substring of length 3 |

Some people suggest to use memset but where should I use it? Edit: No need of memset .I did a silly mistake Last edit: 2015-12-04 18:46:56 |
