You only need to complete the function reverseWord() that takes s as parameter and returns the reversed string.

Expected Time Complexity: O(|S|).
Expected Auxiliary Space: O(1).

Constraints:
1 <= |s| <= 10000

Solution:

# User function template for Python 3
class Solution:
    def reverseWord(self, str: str) -> str:
        # Reverse the given string using slicing (extended slice syntax)
        str = str[::-1]

        # Return the reversed string
        return str

# Driver code
if __name__ == "__main__":
    # Take the number of test cases as input
    t = int(input())
    
    # Iterate through each test case
    while t > 0:
        # Take the input string for each test case
        s = input()
        
        # Create an instance of the Solution class
        ob = Solution()
        
        # Call the reverseWord method and print the result
        print(ob.reverseWord(s))
        
        # Decrement the number of test cases
        t -= 1
