{ "data": { "question": { "questionId": "2168", "questionFrontendId": "2042", "categoryTitle": "Algorithms", "boundTopicId": 1048462, "title": "Check if Numbers Are Ascending in a Sentence", "titleSlug": "check-if-numbers-are-ascending-in-a-sentence", "content": "

A sentence is a list of tokens separated by a single space with no leading or trailing spaces. Every token is either a positive number consisting of digits 0-9 with no leading zeros, or a word consisting of lowercase English letters.

\n\n\n\n

Given a string s representing a sentence, you need to check if all the numbers in s are strictly increasing from left to right (i.e., other than the last number, each number is strictly smaller than the number on its right in s).

\n\n

Return true if so, or false otherwise.

\n\n

 

\n

Example 1:

\n\"example-1\"\n
\nInput: s = "1 box has 3 blue 4 red 6 green and 12 yellow marbles"\nOutput: true\nExplanation: The numbers in s are: 1, 3, 4, 6, 12.\nThey are strictly increasing from left to right: 1 < 3 < 4 < 6 < 12.\n
\n\n

Example 2:

\n\n
\nInput: s = "hello world 5 x 5"\nOutput: false\nExplanation: The numbers in s are: 5, 5. They are not strictly increasing.\n
\n\n

Example 3:

\n\"example-3\"\n
\nInput: s = "sunset is at 7 51 pm overnight lows will be in the low 50 and 60 s"\nOutput: false\nExplanation: The numbers in s are: 7, 51, 50, 60. They are not strictly increasing.\n

Constraints:

\n\n\n", "translatedTitle": "检查句子中的数字是否递增", "translatedContent": "

句子是由若干 token 组成的一个列表，token 间用 单个 空格分隔，句子没有前导或尾随空格。每个 token 要么是一个由数字 0-9 组成的不含前导零的 正整数 ，要么是一个由小写英文字母组成的 单词 。

\n\n\n\n

给你一个表示句子的字符串 s ，你需要检查 s 中的 全部 数字是否从左到右严格递增（即，除了最后一个数字，s 中的 每个 数字都严格小于它 右侧 的数字）。

\n\n

如果满足题目要求，返回 true ，否则，返回 false 。

\n\n

 

\n\n

示例 1：

\n\n

\"example-1\"

\n\n
\n输入：s = \"1 box has 3 blue 4 red 6 green and 12 yellow marbles\"\n输出：true\n解释：句子中的数字是：1, 3, 4, 6, 12 。\n这些数字是按从左到右严格递增的 1 < 3 < 4 < 6 < 12 。\n
\n\n

示例 2：

\n\n
\n输入：s = \"hello world 5 x 5\"\n输出：false\n解释：句子中的数字是：5, 5 。这些数字不是严格递增的。\n
\n\n

示例 3：

\n\n

\"example-3\"

\n\n
\n输入：s = \"sunset is at 7 51 pm overnight lows will be in the low 50 and 60 s\"\n输出：false\n解释：s 中的数字是：7, 51, 50, 60 。这些数字不是严格递增的。\n
\n\n

示例 4：

\n\n
\n输入：s = \"4 5 11 26\"\n输出：true\n解释：s 中的数字是：4, 5, 11, 26 。\n这些数字是按从左到右严格递增的：4 < 5 < 11 < 26 。\n
