You are given a code:

def main_solution(x):
    return func_13(func_5(x, 'lytq'), '|')

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