题目描述

Now that you have proposed a fake post for the HC 2^{2} Facebook page, Heidi wants to measure the quality of the post before actually posting it. She recently came across a (possibly fake) article about the impact of fractal structure on multimedia messages and she is now trying to measure the self-similarity of the message, which is defined as

where the sum is over all nonempty strings pp and is the number of occurences of pp in ss as a substring. (Note that the sum is infinite, but it only has a finite number of nonzero summands.)

Heidi refuses to do anything else until she knows how to calculate this self-similarity. Could you please help her? (If you would like to instead convince Heidi that a finite string cannot be a fractal anyway – do not bother, we have already tried.)

输入格式

The input starts with a line indicating the number of test cases TT ( 1<=T<=101<=T<=10 ). After that, TT test cases follow, each of which consists of one line containing a string ss ( 1<=s<=1000001<=|s|<=100000 ) composed of lowercase letters (a-z).

输出格式

Output TT lines, every line containing one number – the answer to the corresponding test case.

说明/提示

A string ss contains another string pp as a substring if pp is a contiguous subsequence of ss . For example, ab is a substring of cab but not of acb.
