{ "data": { "question": { "questionId": "1934", "questionFrontendId": "1807", "categoryTitle": "Algorithms", "boundTopicId": 678957, "title": "Evaluate the Bracket Pairs of a String", "titleSlug": "evaluate-the-bracket-pairs-of-a-string", "content": "
You are given a string s
that contains some bracket pairs, with each pair containing a non-empty key.
"(name)is(age)yearsold"
, there are two bracket pairs that contain the keys "name"
and "age"
.You know the values of a wide range of keys. This is represented by a 2D string array knowledge
where each knowledge[i] = [keyi, valuei]
indicates that key keyi
has a value of valuei
.
You are tasked to evaluate all of the bracket pairs. When you evaluate a bracket pair that contains some key keyi
, you will:
keyi
and the bracket pair with the key's corresponding valuei
.keyi
and the bracket pair with a question mark "?"
(without the quotation marks).Each key will appear at most once in your knowledge
. There will not be any nested brackets in s
.
Return the resulting string after evaluating all of the bracket pairs.
\n\n\n
Example 1:
\n\n\nInput: s = "(name)is(age)yearsold", knowledge = [["name","bob"],["age","two"]]\nOutput: "bobistwoyearsold"\nExplanation:\nThe key "name" has a value of "bob", so replace "(name)" with "bob".\nThe key "age" has a value of "two", so replace "(age)" with "two".\n\n\n
Example 2:
\n\n\nInput: s = "hi(name)", knowledge = [["a","b"]]\nOutput: "hi?"\nExplanation: As you do not know the value of the key "name", replace "(name)" with "?".\n\n\n
Example 3:
\n\n\nInput: s = "(a)(a)(a)aaa", knowledge = [["a","yes"]]\nOutput: "yesyesyesaaa"\nExplanation: The same key can appear multiple times.\nThe key "a" has a value of "yes", so replace all occurrences of "(a)" with "yes".\nNotice that the "a"s not in a bracket pair are not evaluated.\n\n\n
\n
Constraints:
\n\n1 <= s.length <= 105
0 <= knowledge.length <= 105
knowledge[i].length == 2
1 <= keyi.length, valuei.length <= 10
s
consists of lowercase English letters and round brackets '('
and ')'
.'('
in s
will have a corresponding close bracket ')'
.s
will be non-empty.s
.keyi
and valuei
consist of lowercase English letters.keyi
in knowledge
is unique.给你一个字符串 s
,它包含一些括号对,每个括号中包含一个 非空 的键。
\"(name)is(age)yearsold\"
中,有 两个 括号对,分别包含键 \"name\"
和 \"age\"
。你知道许多键对应的值,这些关系由二维字符串数组 knowledge
表示,其中 knowledge[i] = [keyi, valuei]
,表示键 keyi
对应的值为 valuei
。
你需要替换 所有 的括号对。当你替换一个括号对,且它包含的键为 keyi
时,你需要:
keyi
和括号用对应的值 valuei
替换。knowledge
中无法得知某个键对应的值,你需要将 keyi
和括号用问号 \"?\"
替换(不需要引号)。knowledge
中每个键最多只会出现一次。s
中不会有嵌套的括号。
请你返回替换 所有 括号对后的结果字符串。
\n\n\n\n
示例 1:
\n\n\n输入:s = \"(name)is(age)yearsold\", knowledge = [[\"name\",\"bob\"],[\"age\",\"two\"]]\n输出:\"bobistwoyearsold\"\n解释:\n键 \"name\" 对应的值为 \"bob\" ,所以将 \"(name)\" 替换为 \"bob\" 。\n键 \"age\" 对应的值为 \"two\" ,所以将 \"(age)\" 替换为 \"two\" 。\n\n\n
示例 2:
\n\n\n输入:s = \"hi(name)\", knowledge = [[\"a\",\"b\"]]\n输出:\"hi?\"\n解释:由于不知道键 \"name\" 对应的值,所以用 \"?\" 替换 \"(name)\" 。\n\n\n
示例 3:
\n\n\n输入:s = \"(a)(a)(a)aaa\", knowledge = [[\"a\",\"yes\"]]\n输出:\"yesyesyesaaa\"\n解释:相同的键在 s 中可能会出现多次。\n键 \"a\" 对应的值为 \"yes\" ,所以将所有的 \"(a)\" 替换为 \"yes\" 。\n注意,不在括号里的 \"a\" 不需要被替换。\n\n\n
\n\n
提示:
\n\n1 <= s.length <= 105
0 <= knowledge.length <= 105
knowledge[i].length == 2
1 <= keyi.length, valuei.length <= 10
s
只包含小写英文字母和圆括号 '('
和 ')'
。s
中每一个左圆括号 '('
都有对应的右圆括号 ')'
。s
中每对括号内的键都不会为空。s
中不会有嵌套括号对。keyi
和 valuei
只包含小写英文字母。knowledge
中的 keyi
不会重复。\\u7248\\u672c\\uff1a \\u7f16\\u8bd1\\u65f6\\uff0c\\u5c06\\u4f1a\\u91c7\\u7528
