{ "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
.
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
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
\n
Constraints:
\n\n2 <= number.length <= 100
number
consists of digits from '1'
to '9'
.digit
is a digit from '1'
to '9'
.digit
occurs at least once in number
.给你一个表示某个正整数的字符串 number
和一个字符 digit
。
从 number
中 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 digit
在 number
中出现至少一次。
\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

提示:
\n\n2 <= number.length <= 100
