def remove_first_last_char(string):
    return string[1:-1]

# 示例用法
input_string = "Hello World"
result = remove_first_last_char(input_string)
print(result)

public class Main {
    public static String removeFirstLastChar(String string) {
        return string.substring(1, string.length() - 1);
    }

    // 示例用法
    public static void main(String[] args) {
        String inputString = "Hello World";
        String result = removeFirstLastChar(inputString);
        System.out.println(result);
    }
}

function removeFirstLastChar(string) {
    return string.slice(1, -1);
}

// 示例用法
var inputString = "Hello World";
var result = removeFirstLastChar(inputString);
console.log(result);
