November 12, 2021 - Convert the string into an array of strings, which will store the words. Initialize the 2 pointers left and right to 0 and string.length() – 1 respectively. While the left pointer does not exceed the right pointer, swap the elements at the left and right pointer, move the left pointer forward and the right pointer backward by 1 place. Finally, return the final calculated string. ... string reverseByWords(string s) { vector < string > words; string str = ""; for (char c: s) { if (c == ' ') { words.push_back(str); str = ""; } else { str += c; } } words.push_back(str); int left = 0, right = words.size() - 1; while (left <= right) { swap(words[left], words[right]); left++; right--; } string ans = ""; for (auto x: words) { ans += x; ans += " "; } ans.pop_back(); return ans; }

class Solution { public: string reverseWords(string s) { int l = 0, r = 0, n = s.size(); for (int i = 0; i < n; i++) { // looking for the space index if (s[i] == ' ' || i == n - 1) { // r is the index before the space // if s[i] is space, then we want to reverse s[l : i - 1] // if s[i] is the last character, then we want to reverse s[l : i] r = i == n - 1 ? i : i - 1; // swap the character // e.g. s = `Let's` where l is 0 and r is 4 // Let's -> set'L -> s'teL while (l < r) swap(s[l++], s[r--]); // update left pointer which is i + 1 // i.e. the first index of the next word if applicable l = i +
