You are given a code:

def main_solution(x):
    return func_20(func_15('uorf'), ('chfl' + x))

Can you predict the output of `main_solution("anozxrkc")` without writing any code? Please reason and put your final answer in the following json format: {"output": <your output>}, where <your output> should be the final string.
