Implement a function that moves the first character of a string to the end, returning the transformed string. If the input is empty, return an empty string.
Examples:
rotate_left("hello")returnsellohrotate_left("a")returnsarotate_left("")returns""
def rotate_left(s: str) -> str:\n pass
Rules:
- Any language or pseudocode is fine. The stub just shows the shape.
- Say the time complexity of your approach.
- short rule
- one well defined function with input and output
- 2 to 4 word topic label
