2109 - Adding Spaces to a String\. Medium 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. * For example, given `s = "EnjoyYourCoffee"` and `spaces = [5, 9]`, we place spaces before `'Y'` and `'C'`, which are at indices `5` and `9` respectively. Thus, we obtain `"Enjoy **Y**our **C**offee"`. Return _the modified string **after** the spaces have been added._ **Example 1:** **Input:** s = "LeetcodeHelpsMeLearn", spaces = [8,13,15] **Output:** "Leetcode Helps Me Learn" **Explanation:** The indices 8, 13, and 15 correspond to the underlined characters in "Leetcode**H**elps**M**e**L**earn". We then place spaces before those characters. **Example 2:** **Input:** s = "icodeinpython", spaces = [1,5,7,9] **Output:** "i code in py thon" **Explanation:** The indices 1, 5, 7, and 9 correspond to the underlined characters in "i**c**ode**i**n**p**y**t**hon". We then place spaces before those characters. **Example 3:** **Input:** s = "spacing", spaces = [0,1,2,3,4,5,6] **Output:** " s p a c i n g" **Explanation:** We are also able to place spaces before the first character of the string. **Constraints:** * 1 <= s.length <= 3 * 105 * `s` consists only of lowercase and uppercase English letters. * 1 <= spaces.length <= 3 * 105 * `0 <= spaces[i] <= s.length - 1` * All the values of `spaces` are **strictly increasing**.
