CF1398B.Substring Removal Game

Alice and Bob play a game. They have a binary string $s$ (a string such that each character in it is either $0$ or $1$ ). Alice moves first, then Bob, then Alice again, and so on.

During their move, the player can choose any number (not less than one) of consecutive equal characters in $s$ and delete them.

For example, if the string is $10110$ , there are $6$ possible moves (deleted characters are bold):

1. $\textbf{1}0110 \to 0110$ ;
2. $1\textbf{0}110 \to 1110$ ;
3. $10\textbf{1}10 \to 1010$ ;
4. $101\textbf{1}0 \to 1010$ ;
5. $10\textbf{11}0 \to 100$ ;
6. $1011\textbf{0} \to 1011$ .

After the characters are removed, the characters to the left and to the right of the removed block become adjacent. I. e. the following sequence of moves is valid: $10\textbf{11}0 \to 1\textbf{00} \to 1$ .

The game ends when the string becomes empty, and the score of each player is the number of $1$ -characters deleted by them.

Each player wants to maximize their score. Calculate the resulting score of Alice.

The first line contains one integer $T$ ( $1 \le T \le 500$ ) — the number of test cases.

Each test case contains exactly one line containing a binary string $s$ ( $1 \le |s| \le 100$ ).

For each test case, print one integer — the resulting score of Alice (the number of $1$ -characters deleted by her).

Questions about the optimal strategy will be ignored.
