One day, Chef prepared D brand new dishes. He named the i-th dish by a string Si. After the cooking, he decided to categorize each of these D dishes as special or not.

A dish Si is called special if it's name (i.e. the string Si) can be represented in the form of a double string by removing at most one (possibly zero) character from it's name from any position. 

A string is called a double string if it can be represented as a concatenation of two identical, non-empty strings. 
e.g. "abab" is a double string as it can be represented as "ab" + "ab" where + operation denotes concatenation. 
Similarly, "aa", "abcabc" are double strings whereas "a", "abba", "abc" are not.

-----Input-----
- First line of the input contains an integer D denoting the number of dishes prepared by Chef on that day.
- Each of the next D lines will contain description of a dish. 
	
- The i-th line contains the name of i-th dish Si.
	

-----Output-----
For each of the D dishes, print a single line containing "YES" or "NO" (without quotes) denoting whether the dish can be called as a special or not.

-----Constraints-----
- 1 ≤ D ≤ 106
- 1 ≤ |Si| ≤ 106.
- Each character of string Si will be lower case English alphabet (i.e. from 'a' to 'z').

-----Subtasks-----
Subtask #1 : (20 points)
- Sum of |Si| in an input file doesn't exceed 2 * 103

Subtask 2 : (80 points) 
- Sum of |Si| in an input file doesn't exceed 2 * 106

-----Example-----
Input:
3
aba
abac
abcd

Output:
YES
NO
NO


-----Explanation-----
Example case 1.
We can remove the character at position 1 (0-based index) to get "aa" which is a double string. Hence, it is a special dish.

Example case 2.
It is not possible to remove the character at any of the position to get the double string. Hence, it is not a special dish.
