- Step 2: Append each character to a new string in reverse order.
- Step 3: Return the new reversed string.
- Step 4: For "hello", the reversed string is "olleh".
Example 2
- Input: s = "Python"
- Output: "nohtyP"
- Explanation:
- Step 1: Traverse the string from end to beginning.
- Step 2: Append each character to a new string in reverse order.
- Step 3: Return the new reversed string.
- Step 4: For "Python", the reversed string is "nohtyP".
Constraints
- 1 ≤ len(string) ≤ 10^6
- The string contains printable ASCII characters.
- Time Complexity: O(n), where n is the length of the string.
- Space Complexity: O(n)
