We define str = [s, n] as the string str which consists of the string s concatenated n times.

\n\n\n\n

We define that string s1 can be obtained from string s2 if we can remove some characters from s2 such that it becomes s1.

\n\n\n\n

You are given two strings s1 and s2 and two integers n1 and n2. You have the two strings str1 = [s1, n1] and str2 = [s2, n2].

\n\n

Return the maximum integer m such that str = [str2, m] can be obtained from str1.

\n\n

 

\n

Example 1:

\n
Input: s1 = \"acb\", n1 = 4, s2 = \"ab\", n2 = 2\nOutput: 2\n

Example 2:

\n
Input: s1 = \"acb\", n1 = 1, s2 = \"acb\", n2 = 1\nOutput: 1\n

Constraints:

\n\n\n", "translatedTitle": "统计重复个数", "translatedContent": "

定义 str = [s, n] 表示 strn 个字符串 s 连接构成。

\n\n\n\n

如果可以从 s2 中删除某些字符使其变为 s1,则称字符串 s1 可以从字符串 s2 获得。

\n\n\n\n

现在给你两个字符串 s1 和 s2 和两个整数 n1n2 。由此构造得到两个字符串,其中 str1 = [s1, n1]str2 = [s2, n2]

\n\n

请你找出一个最大整数 m ,以满足 str = [str2, m] 可以从 str1 获得。

\n\n

 

\n\n

示例 1:

\n\n
\n输入:s1 = \"acb\", n1 = 4, s2 = \"ab\", n2 = 2\n输出:2\n
\n\n

示例 2:

\n\n
\n输入:s1 = \"acb\", n1 = 1, s2 = \"acb\", n2 = 1\n输出:1\n
