You are given a code:

def main_solution(x):
    return func_5(func_20('dhvru', 'cdaoy'), 'yqjf')

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