You are given a code:

def main_solution(x):
    return (func_4('gjpkms') + func_5('zhm', 'agn'))

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