Reverse String LeetCode

reverseString.js

/*
Write a function that reverses a string. The input string is given as an array of characters s.
 
Example 1:
Input: s = ["h","e","l","l","o"]
Output: ["o","l","l","e","h"]
Example 2:
Input: s = ["H","a","n","n","a","h"]
Output: ["h","a","n","n","a","H"]
 
Constraints:
1 <= s.length <= 105
s[i] is a printable ascii character.
 
Follow up: Do not allocate extra space for another array. You must do this by modifying the input array in-place with O(1) extra memory.
*/
/**
 * @param {character[]} s
 * @return {void} Do not return anything, modify s in-place instead.
 */
const s = ['h', 'e', 'l', 'l', 'o'];
const reverseString = (s) => {
    let reversedArray = [];
    for (let i = s.length - 1; i >= 0; i--) {
        reversedArray.push(s[i]);
    }
    for (let i = 0; i < reversedArray.length; i ++) {
        s[i] = reversedArray[i];
    }
    return s;
};

console.log(reverseString(s));
