{ "data": { "question": { "questionId": "2372", "questionFrontendId": "2287", "categoryTitle": "Algorithms", "boundTopicId": 1520503, "title": "Rearrange Characters to Make Target String", "titleSlug": "rearrange-characters-to-make-target-string", "content": "

You are given two 0-indexed strings s and target. You can take some letters from s and rearrange them to form new strings.

\n\n

Return the maximum number of copies of target that can be formed by taking letters from s and rearranging them.

\n\n

 

\n

Example 1:

\n\n
\nInput: s = "ilovecodingonleetcode", target = "code"\nOutput: 2\nExplanation:\nFor the first copy of "code", take the letters at indices 4, 5, 6, and 7.\nFor the second copy of "code", take the letters at indices 17, 18, 19, and 20.\nThe strings that are formed are "ecod" and "code" which can both be rearranged into "code".\nWe can make at most two copies of "code", so we return 2.\n
\n\n

Example 2:

\n\n
\nInput: s = "abcba", target = "abc"\nOutput: 1\nExplanation:\nWe can make one copy of "abc" by taking the letters at indices 0, 1, and 2.\nWe can make at most one copy of "abc", so we return 1.\nNote that while there is an extra 'a' and 'b' at indices 3 and 4, we cannot reuse the letter 'c' at index 2, so we cannot make a second copy of "abc".\n
\n\n

Example 3:

\n\n
\nInput: s = "abbaccaddaeea", target = "aaaaa"\nOutput: 1\nExplanation:\nWe can make one copy of "aaaaa" by taking the letters at indices 0, 3, 6, 9, and 12.\nWe can make at most one copy of "aaaaa", so we return 1.\n
\n\n

 

\n

Constraints:

\n\n\n", "translatedTitle": "重排字符形成目标字符串", "translatedContent": "

给你两个下标从 0 开始的字符串 starget 。你可以从 s 取出一些字符并将其重排,得到若干新的字符串。

\n\n

s 中取出字符并重新排列,返回可以形成 target最大 副本数。

\n\n

 

\n\n

示例 1:

\n\n
输入:s = \"ilovecodingonleetcode\", target = \"code\"\n输出:2\n解释:\n对于 \"code\" 的第 1 个副本,选取下标为 4 、5 、6 和 7 的字符。\n对于 \"code\" 的第 2 个副本,选取下标为 17 、18 、19 和 20 的字符。\n形成的字符串分别是 \"ecod\" 和 \"code\" ,都可以重排为 \"code\" 。\n可以形成最多 2 个 \"code\" 的副本,所以返回 2 。\n
\n\n

示例 2:

\n\n
输入:s = \"abcba\", target = \"abc\"\n输出:1\n解释:\n选取下标为 0 、1 和 2 的字符,可以形成 \"abc\" 的 1 个副本。 \n可以形成最多 1 个 \"abc\" 的副本,所以返回 1 。\n注意,尽管下标 3 和 4 分别有额外的 'a' 和 'b' ,但不能重用下标 2 处的 'c' ,所以无法形成 \"abc\" 的第 2 个副本。\n
\n\n

示例 3:

\n\n
输入:s = \"abbaccaddaeea\", target = \"aaaaa\"\n输出:1\n解释:\n选取下标为 0 、3 、6 、9 和 12 的字符,可以形成 \"aaaaa\" 的 1 个副本。\n可以形成最多 1 个 \"aaaaa\" 的副本,所以返回 1 。\n
