我们应该编写一个计算机科学程序，计算出你是在一周中的哪一天出生的。我们得到了这些指示。1) 从您出生年份的最后两位数字开始。2) 将上述数字除以 4，如果有 1，则舍去余数。3) 在月份表中找到与您出生月份相关的数字。4) 你的生日是一个月中的哪一天？5) 求在步骤 1 到 4 中获得的四个数字的总和。 6) 将总和除以数字 7。对应于天数表中余数的日期是您出生的星期几。
月表 日表
1 月 1 日（闰年 0） 2 月 1
日星期日（闰年 3） 3 月 2

我一直在遇到无法比较的类型的问题：int 和 boolean，我不知道问题是什么，我尝试将变量更改为 boolean，但它没有解决任何问题。
