You are given a code:

def main_solution(x):
    return (func_5('biea', 'xyob') + func_17('blesx'))

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