You are given a code:

def main_solution(x):
    return func_5(func_5('mbscfo', 'vlba'), 'otkl')

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