Can you please tell me how to get rid of the error…

NZEC means “Non zero exit code”. Its essentially saying that your program ran into some error during execution**

https://www.codechef.com/wiki/faq#Why_do_I_get_an_NZEC
i comented lines which were causing runtime error–

            }
        }
    }

Now no NZEC error but Giving wrong answer… so try to correct ur logic and submit it
