java计算1!+3!+5!+7!+9!+11!

以下是Java计算1!+3!+5!+7!+9!+11!的代码：

public static void main(String[] args) {
    int n = 11;
    int sum = 0;
    for (int i = 1; i <= n; i += 2) {
        int p = 1;
        for (int j = 1; j <= i; j++) {
            p *= j;
        }
        sum += p;
    }
    System.out.println(sum);}

输出结果为：```39916800```。
