Develop a Python function to compute the final cardinal direction given the number of turns and turn directions.
Implement a function `find_final_direction(n: int, directions: str)`, which simulates a series of turns from an initial North-facing position and returns the final direction faced. The cardinal directions are represented as N (north), S (south), E (east), or W (west). ### Parameters - `n` (int): An integer that specifies the number of turns. It ranges from 1 to 10000. - `directions` (str): A string comprised of `n` elements, with each element being either 'l' (representing a left turn) or 'r' (indicating a right turn). ### Return Value - The function should return a string that signifies the cardinal direction the person would end up facing after performing all given turns. The output would be one of 'N', 'S', 'E', or 'W'. ### Examples ```python find_final_direction(3, "lrr") # E find_final_direction(5, "rrrrl") # N find_final_direction(5, "rlrll") # W ```
