题目描述

You are given a string ss consisting of characters 0 and/or 1.

You have to remove several (possibly zero) characters from the beginning of the string, and then several (possibly zero) characters from the end of the string. The string may become empty after the removals. The cost of the removal is the maximum of the following two values:

  • the number of characters 0 left in the string;
  • the number of characters 1 removed from the string.

What is the minimum cost of removal you can achieve?

输入格式

The first line contains one integer tt ( 1t1041 \le t \le 10^4 ) — the number of test cases.

Each test case consists of one line containing the string ss ( 1s21051 \le |s| \le 2 \cdot 10^5 ), consisting of characters 0 and/or 1.

The total length of strings ss in all test cases does not exceed 21052 \cdot 10^5 .

输出格式

For each test case, print one integer — the minimum cost of removal you can achieve.

说明/提示

Consider the test cases of the example:

  1. in the first test case, it's possible to remove two characters from the beginning and one character from the end. Only one 1 is deleted, only one 0 remains, so the cost is 11 ;
  2. in the second test case, it's possible to remove three characters from the beginning and six characters from the end. Two characters 0 remain, three characters 1 are deleted, so the cost is 33 ;
  3. in the third test case, it's optimal to remove four characters from the beginning;
  4. in the fourth test case, it's optimal to remove the whole string;
  5. in the fifth test case, it's optimal to leave the string as it is.
