SUBST1 - New 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 <= 50000

Output

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

Example

Input:
2
CCCCC
ABABA

Output:
5
9

I am using n*logn*logn solution with array of structure for buiding suffix array and still getting TLE. and for lcp i am using kasai's algo. Please help me.
Taking help from : https://discuss.codechef.com/questions/21385/a-tutorial-on-suffix-arrays

n*logn*logn AC

2 days to figure out by taking little help..nice problem

Why does O(nlogn) (suffix array using radix sort) time out ?

nlognlogn =tle nlogn=ac better to learn nlogn found this useful

Optimized nlog^2n gets passed in 0.12s, while nlogn passes in 0.14s. I dont know why??

nlogn(used radix sort everytime) with pointer optimisation got accepted though 0.27 seconds :( ,any ideas for better implementation

For java, use the O(n) version. It got AC in 0.15s

Takes 0.5s in java! anybody managed in java?

Seems that Rodrigo Horruitiner was right and my previous summary comment on this problem is wrong, O(n) is slower than O(n*log(n)) because of radix constant :p
