You are given a code:

def main_solution(x):
    return (func_1('yyysd', 3) + func_11('fxvif', 4))

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