The input string is given as an array of characters s. You must do this by modifying the input array in-place [https://en.wikipedia.org/wiki/In-place_algorithm] with O(1) extra memory.

The problem states that we need to reverse a string which is in a format of a character array · The following constraints are given in the question ... We'll start with two pointers i.e. left and right which will point to start and end of the array respectively · We will loop over array till left pointer is less than right pointer and swap the value at both the pointers iteratively · We have discussed the approach, I urge you to go ahead on leetcode and give it another try.

var reverseWords = function(s) { let temp = s.split(' '); temp.forEach((v,i)=>{ temp[i] = v.split('').reverse().join('') }) return temp.join(' ') };

October 18, 2021 - I’m not sure why the question is posed as a string reversal when the input is already an array but here we go… · This is my solution, which has a runtime of 199ms (beats 9.95% of JS solutions) and memory usage of 46.1MB (beats 67% of JS solutions). I toyed with having a variable halfLength for the loop, which sometimes lowered memory usage significantly but also increased runtime. I get different numbers every time I submit a LeetCode solution so it’s basically a toss up and I went with a cleaner version without the variable.
