You are given a code:

def main_solution(x):
    return func_20(func_9('ysh'), func_13(x, '-'))

Can you predict the output of `main_solution("kkargbgclq")` 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.
