Rust 中使用 std::io 处理输入并解析布尔值：错误处理和修复

The error message suggests that there's an issue with parsing a boolean value from the input. To fix this, you can add error handling for the parse method.

Replace this line:

let row: Vec<bool> = lines.next().unwrap().split_whitespace().map(|x| x.parse().unwrap()).collect();

With this line:

let row: Vec<bool> = lines.next().unwrap().split_whitespace().map(|x| x.parse().unwrap_or(false)).collect();

This change will set the value to false if the parsing fails, instead of panicking with the unwrap method.
