def main_solution(x):
    return (func_19('ujexlw', 2) + ('qpypid' + 'fixcjm'))

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