You are given a code:

def main_solution(x):
    return (func_15('atlys') + func_13('cllfh', '|'))

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