{ "data": { "question": { "questionId": "2337", "questionFrontendId": "2259", "categoryTitle": "Algorithms", "boundTopicId": 1456876, "title": "Remove Digit From Number to Maximize Result", "titleSlug": "remove-digit-from-number-to-maximize-result", "content": "

You are given a string number representing a positive integer and a character digit.

\n\n

Return the resulting string after removing exactly one occurrence of digit from number such that the value of the resulting string in decimal form is maximized. The test cases are generated such that digit occurs at least once in number.

\n\n

 

\n

Example 1:

\n\n
\nInput: number = "123", digit = "3"\nOutput: "12"\nExplanation: There is only one '3' in "123". After removing '3', the result is "12".\n
\n\n

Example 2:

\n\n
\nInput: number = "1231", digit = "1"\nOutput: "231"\nExplanation: We can remove the first '1' to get "231" or remove the second '1' to get "123".\nSince 231 > 123, we return "231".\n
\n\n

Example 3:

\n\n
\nInput: number = "551", digit = "5"\nOutput: "51"\nExplanation: We can remove either the first or second '5' from "551".\nBoth result in the string "51".\n
\n\n

Constraints:

\n\n\n", "translatedTitle": "移除指定数字得到的最大结果", "translatedContent": "

给你一个表示某个正整数的字符串 number 和一个字符 digit

\n\n

number恰好 移除 一个 等于 digit 的字符后,找出并返回按 十进制 表示 最大 的结果字符串。生成的测试用例满足 digitnumber 中出现至少一次。

\n\n

 

\n\n

示例 1:

\n\n
\n输入:number = \"123\", digit = \"3\"\n输出:\"12\"\n解释:\"123\" 中只有一个 '3' ,在移除 '3' 之后,结果为 \"12\" 。\n
\n\n

示例 2:

\n\n
\n输入:number = \"1231\", digit = \"1\"\n输出:\"231\"\n解释:可以移除第一个 '1' 得到 \"231\" 或者移除第二个 '1' 得到 \"123\" 。\n由于 231 > 123 ,返回 \"231\" 。\n
\n\n

示例 3:

\n\n
\n输入:number = \"551\", digit = \"5\"\n输出:\"51\"\n解释:可以从 \"551\" 中移除第一个或者第二个 '5' 。\n两种方案的结果都是 \"51\" 。\n
\n\n
