Skibidus is given a string ss that consists of lowercase Latin letters. If ss contains more than 11 letter, he can:
- Choose an index ii (1≤i≤|s|−11≤i≤|s|−1, |s||s| denotes the current length of ss) such that si=si+1si=si+1. Replace sisi with any lowercase Latin letter of his choice. Remove si+1si+1 from the string.
Skibidus must determine the minimum possible length he can achieve through any number of operations.
Input
The first line contains an integer tt (1≤t≤1001≤t≤100) --- the number of test cases.
The only line of each test case contains a string ss (1≤|s|≤1001≤|s|≤100). It is guaranteed ss only contains lowercase Latin letters.
Output
For each test case, output an integer on the new line, the minimum achievable length of ss.

In the first test case, Skibidus can:
- Perform an operation on i=2i=2. He replaces s2s2 with b and removes s3s3 from the string. Then, ss becomes bb.
- Perform an operation on i=1i=1. He replaces s1s1 with b and removes s2s2 from the string. Then, ss becomes b.
- Because ss only contains 11 letter, Skibidus cannot perform any more operations.
Therefore, the answer is 11 for the first test case.
In the second test case, he cannot perform an operation on any index. Therefore, the answer is still the length of the initial string, 88.
解题说明：此题是一道字符串题，找规律能发现，只要存在两个连续相同的字母就能继续执行，因为每次删除时都能将选中的字母变成前面的字母，这样就能不断删除后面的字母，直到为1，所以答案要么为1要么就是字符串长度。
