You are given a code:

def main_solution(x):
    return (func_13('qxycg', '-') + func_23('wdcph', 1))

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