DISUBSTR - Distinct Substrings

no tags 

Given a string, we need to find the total number of its distinct substrings.


T- number of test cases. T<=20;
Each test case consists of one string, whose length is <= 1000


For each test case output one number saying the number of distinct substrings.


Sample Input:

Sample Output:

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.

Suffix array :D

kmp rocks :)

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

0.00 suffix array rocks

AAA is also a possible substring of length 3

Simple Suffix Array (O(n*lg^2n)) with lcp

Anybody getting TLE in Java?

Some people suggest to use memset but where should I use it?

Edit: No need of memset .I did a silly mistake
