You are given a code:

def main_solution(x):
    return (('fwuty' + 'uwtjt') + ('ejbqsu' + 'hfbfn'))

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