Good day. So today I was trying to solve this problem 580C - Kefa and Park but as soon as I submitted it I got a wrong answer on test 1 I tried the input of test one locally and it gave a right answer but submitting it gives a wrong answer I double checked the compiler that I was using and I didn't get anywhere. Do you have an idea what's going on??? here's my submission 18172263. Thanks in advance.
