Problem Description
You heart broke into pieces.My string broke into pieces.But you will recover one day,and my string will never go back.
Given a string s.We can erase a subsequence of it if this subsequence is palindrome in one step.We should take as few steps as possible to erase the whole sequence.How many steps do we need
For example, we can erase abcba from axbyczbea and get xyze in one step.

Input
The first line contains integer T,denote the number of the test cases. Then T lines follows,each line contains the string s (1<= length of s <= 16).
T<=10.

Output
For each test cases,print the answer in a line.
