{ "data": { "question": { "questionId": "2232", "questionFrontendId": "2109", "categoryTitle": "Algorithms", "boundTopicId": 1161395, "title": "Adding Spaces to a String", "titleSlug": "adding-spaces-to-a-string", "content": "

You are given a 0-indexed string s and a 0-indexed integer array spaces that describes the indices in the original string where spaces will be added. Each space should be inserted before the character at the given index.

\n\n\n\n

Return the modified string after the spaces have been added.

\n\n

 

\n

Example 1:

\n\n
\nInput: s = "LeetcodeHelpsMeLearn", spaces = [8,13,15]\nOutput: "Leetcode Helps Me Learn"\nExplanation: \nThe indices 8, 13, and 15 correspond to the underlined characters in "LeetcodeHelpsMeLearn".\nWe then place spaces before those characters.\n
\n\n

Example 2:

\n\n
\nInput: s = "icodeinpython", spaces = [1,5,7,9]\nOutput: "i code in py thon"\nExplanation:\nThe indices 1, 5, 7, and 9 correspond to the underlined characters in "icodeinpython".\nWe then place spaces before those characters.\n
\n\n

Example 3:

\n\n
\nInput: s = "spacing", spaces = [0,1,2,3,4,5,6]\nOutput: " s p a c i n g"\nExplanation:\nWe are also able to place spaces before the first character of the string.\n
\n\n

 

\n

Constraints:

\n\n\n", "translatedTitle": "向字符串添加空格", "translatedContent": "

给你一个下标从 0 开始的字符串 s ，以及一个下标从 0 开始的整数数组 spaces 。

\n\n

数组 spaces 描述原字符串中需要添加空格的下标。每个空格都应该插入到给定索引处的字符值 之前 。

\n\n\n\n

请你添加空格，并返回修改后的字符串。

\n\n

 

\n\n

示例 1：

\n\n
\n输入：s = \"LeetcodeHelpsMeLearn\", spaces = [8,13,15]\n输出：\"Leetcode Helps Me Learn\"\n解释：\n下标 8、13 和 15 对应 \"LeetcodeHelpsMeLearn\" 中加粗斜体字符。\n接着在这些字符前添加空格。\n
\n\n

示例 2：

\n\n
\n输入：s = \"icodeinpython\", spaces = [1,5,7,9]\n输出：\"i code in py thon\"\n解释：\n下标 1、5、7 和 9 对应 \"icodeinpython\" 中加粗斜体字符。\n接着在这些字符前添加空格。\n
\n\n

示例 3：

\n\n
\n输入：s = \"spacing\", spaces = [0,1,2,3,4,5,6]\n输出：\" s p a c i n g\"\n解释：\n字符串的第一个字符前可以添加空格。\n
\n\n
