You are given a code:

def main_solution(x):
    return func_20((x + 'lwx'), func_15('azj'))

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