Adding Spaces to a String
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.
Return the modified string after the spaces have been added.
Example 1
Input
s = "LeetcodeHelpsMeLearn", spaces = [8,13,15]Output
"Leetcode Helps Me Learn"The indices 8, 13, and 15 correspond to the characters where spaces are inserted before them.
Example 2
Input
s = "icodeinpython", spaces = [1,5,7,9]Output
"i code in py thon"The indices 1, 5, 7, and 9 correspond to the characters where spaces are inserted before them.
Constraints
- 1 <= s.length <= 3 * 10^5
sconsists only of lowercase and uppercase English letters.- 1 <= spaces.length <= 3 * 10^5
- 0 <= spaces[i] <= s.length - 1
- All the values of
spacesare strictly increasing.
