使用循环计算+𝐬=𝟏/𝟏!−𝟏/𝟐!+𝟏/𝟑!−𝟏/𝟒!+…+𝟏/𝟗𝟗!−𝟏/𝟏𝟎𝟎!+的值

可以使用循环来计算+𝐬=𝟏/𝟏!−𝟏/𝟐!+𝟏/𝟑!−𝟏/𝟒!+…+𝟏/𝟗𝟗!−𝟏/𝟏𝟎𝟎!+的值。具体实现可以参考以下代码：

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("请输入n的值：");
        int n = scanner.nextInt();
        double sum = 0;
        int sign = 1;
        for (int i = 1; i <= n; i++) {
            double factorial = 1;
            for (int j = 1; j <= i; j++) {
                factorial *= j;
            }
            sum += sign / factorial;
            sign = -sign;
        }
        System.out.println("计算结果为：" + sum);
    }
}
