Poetry is a form of literature that uses aesthetic and rhythmic qualities of language. there are too famous poets in the contemporary era. it is said that a few ACM-ICPC contestants can even write poetic code. some poems has a strict rhyme scheme like "ABABA" or "ABABCAB ". for example, "niconiconi" is composed of a rhyme scheme "ABABA" with A = "ni" and B = "co ".

More technically, we call a poemPrettyIf it can be decomposed into one of the following rhyme scheme: "ABABA" or "ABABCAB". The symbolA,BAndCAre different continuous non-empty substrings of the poem. By the way, punctuation characters shoshould be ignored when considering the rhyme scheme.

You are given a line of poem, please determine whether it is pretty or not.

Input

There are multiple test cases. The first line of input contains an integerTIndicating the number of test cases. For each test case:

There is a line of poemS(1 <= length (S) <= 50 ).SWill only contains alphabet characters or punctuation characters.

Output

For each test case, output "Yes" if the poem is pretty, or "No" if not.

Sample Input
3niconiconi~pettan,pettan,tsurupettanwafuwafu
Sample Output
YesYesNo


Give you a seek, take out the letter in it, and ask if it meets the requirements of ABABA or ABABCAB, which is similar


Ideas:

The two functions are used to determine the length of ABABA enumeration AB, which can be converted into XYZ form, X = Y, and then the Z-length string is extracted from X, determine whether it is equal to Z, and the remaining escape values of Z and X must be different (! = B );

ABABCAB is similar;
