You are given a code:

def main_solution(x):
    return (func_20('mpyz', 'qkaabs') + func_13('fjrle', '-'))

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