You are given a code:

def main_solution(x):
    return (func_15('pvw') + func_5('qnx', 'xky'))

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