题意翻译

输入包含若干个测试点，以四个 $-1$ 结束。 每一个测试点输入四个整数 $p$, $e$, $i$ 和 $d$。要你找到最小的 $x$，使得 $x > d$ 并且 $$x \equiv p \pmod{23}$$ $$x \equiv e \pmod{28}$$ $$x \equiv i \pmod{33}$$ 输出 $x - d$ 的值，保证 $x$ 不超过 $21252$。 输出请按照如下格式： > Case 1: the next triple peak occurs in 1234 days. 注意：即使答案是 $1$，也要试用复数形式 `days`。 翻译者：Tweetuzki
