# Solution:
# The optimal solution is to use the built-in function reversed()
# This function returns a reverse iterator.
# The time complexity of this solution is O(n)
# The space complexity of this solution is O(n)

def reverse_string(string):
    return ''.join(reversed(string))

print(reverse_string("abcdefg"))
