Substring Removal Game
Description
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):
- $\textbf{1}0110 \to 0110$;
- $1\textbf{0}110 \to 1110$;
- $10\textbf{1}10 \to 1010$;
- $101\textbf{1}0 \to 1010$;
- $10\textbf{11}0 \to 100$;
- $1011\textbf{0} \to 1011$.
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).
