Write a Python program to reverse a given string.

Example 1
    
  
  • Input: s = "hello"
    • 
  
  • Output: "olleh"
    • 
  
  • 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 "hello", the reversed string is "olleh".
      •

  • Explanation: 
    
      
      
    • Step 1: Traverse the string from end to beginning.
      • 
      
    • Step 2: Append each character to a new string in reverse order.
      •

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)

  • Use slicing to reverse the string: s[::-1]
    • 
  
  • Use a loop to build the reversed string.
    • 
  
  • Handle edge cases where the string is empty or has only one character.
