You are given a code:

def main_solution(x):
    return (func_5('whainq', 'sfd') + func_13('wwqgzv', '|'))

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