Usaco。星期五十三。我的代码有什么问题？ [英] Usaco. Friday the thirteen. What is wrong with my code?

问题描述

我已经为USACO任务制定了一个程序，现在我不知道为什么我得到了错误的答案，我一直在想为什么很长时间，仍然没有想出来。什么可能是错误的？

I've made a program for the USACO task and now I just can't figure out why I'm getting the bad answer, I've been thinking why for a long time and still didn't figure it out. What could be wrong?

任务是计算第13个星期六，星期日，星期一，星期二，...，星期五的次数。

The task is to count the number of times the 13th falls on Saturday, Sunday, Monday, Tuesday, ..., Friday. The year from when to test is 1900 and the last year is given in the txt file.

而不是这个答案：36 33 34 33 35 35 34

Instead of this answer: 36 33 34 33 35 35 34

我得到：34 33 33 33 36 36 35

I'm getting: 34 33 33 33 36 36 35

}

推荐答案

。

2月是第2个月，而不是第5个月。

第二个月没有30天已存活）。

February is the 2nd month, not the 5th.
As the second month, it doesn't have 30 days (at least since I've been alive).

您可能要交换这些常量。

You may want to swap those constants.
