{ "data": { "question": { "questionId": "3245", "questionFrontendId": "3006", "categoryTitle": "Algorithms", "boundTopicId": 2600366, "title": "Find Beautiful Indices in the Given Array I", "titleSlug": "find-beautiful-indices-in-the-given-array-i", "content": "
You are given a 0-indexed string s
, a string a
, a string b
, and an integer k
.
An index i
is beautiful if:
0 <= i <= s.length - a.length
s[i..(i + a.length - 1)] == a
j
such that:\n\t0 <= j <= s.length - b.length
s[j..(j + b.length - 1)] == b
|j - i| <= k
Return the array that contains beautiful indices in sorted order from smallest to largest.
\n\n\n
Example 1:
\n\n\nInput: s = "isawsquirrelnearmysquirrelhouseohmy", a = "my", b = "squirrel", k = 15\nOutput: [16,33]\nExplanation: There are 2 beautiful indices: [16,33].\n- The index 16 is beautiful as s[16..17] == "my" and there exists an index 4 with s[4..11] == "squirrel" and |16 - 4| <= 15.\n- The index 33 is beautiful as s[33..34] == "my" and there exists an index 18 with s[18..25] == "squirrel" and |33 - 18| <= 15.\nThus we return [16,33] as the result.\n\n\n
Example 2:
\n\n\nInput: s = "abcd", a = "a", b = "a", k = 4\nOutput: [0]\nExplanation: There is 1 beautiful index: [0].\n- The index 0 is beautiful as s[0..0] == "a" and there exists an index 0 with s[0..0] == "a" and |0 - 0| <= 4.\nThus we return [0] as the result.\n\n\n
\n
Constraints:
\n\n1 <= k <= s.length <= 105
1 <= a.length, b.length <= 10
s
, a
, and b
contain only lowercase English letters.给你一个下标从 0 开始的字符串 s
、字符串 a
、字符串 b
和一个整数 k
。
如果下标 i
满足以下条件,则认为它是一个 美丽下标:
0 <= i <= s.length - a.length
s[i..(i + a.length - 1)] == a
j
使得:\n\t0 <= j <= s.length - b.length
s[j..(j + b.length - 1)] == b
|j - i| <= k
以数组形式按 从小到大排序 返回美丽下标。
\n\n\n\n
示例 1:
\n\n\n输入:s = \"isawsquirrelnearmysquirrelhouseohmy\", a = \"my\", b = \"squirrel\", k = 15\n输出:[16,33]\n解释:存在 2 个美丽下标:[16,33]。\n- 下标 16 是美丽下标,因为 s[16..17] == \"my\" ,且存在下标 4 ,满足 s[4..11] == \"squirrel\" 且 |16 - 4| <= 15 。\n- 下标 33 是美丽下标,因为 s[33..34] == \"my\" ,且存在下标 18 ,满足 s[18..25] == \"squirrel\" 且 |33 - 18| <= 15 。\n因此返回 [16,33] 作为结果。\n\n\n
示例 2:
\n\n\n输入:s = \"abcd\", a = \"a\", b = \"a\", k = 4\n输出:[0]\n解释:存在 1 个美丽下标:[0]。\n- 下标 0 是美丽下标,因为 s[0..0] == \"a\" ,且存在下标 0 ,满足 s[0..0] == \"a\" 且 |0 - 0| <= 4 。\n因此返回 [0] 作为结果。\n\n\n
\n\n
提示:
\n\n1 <= k <= s.length <= 105
1 <= a.length, b.length <= 10
s
、a
、和 b
只包含小写英文字母。i
, you can iterate over all j
s and determine if i
is beautiful or not."
