def main_solution(x):
    return (('bdigzx').capitalize() + func_15('ewyyy'))

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