Hello — I am very new so I'm not sure if I'm not having proper etiquette — please inform me if I'm being rude etc. ↵

The problem is about finding the numerical ID of a string. So A = 1, B = 2, etc. AA = 27 (since it goes to Z then it becomes AA — kind of like an excel sheet.) ↵
↵
I thought I solved this,([my code](https://codeforces.com/a7a3e1/Screenshot 2023-04-01 at 2.36.14 pm/predownloaded/bb/f5/bbf52ab5968717e14f2cab66a72793673fd1280e.png) is the first screenshot)↵
- I just thought that the ID is: eg ABC — the 'A' spot is 26^2, and the value of A is 1, 'B' spot is the 26^1 spot, and the value of B is 2, etc. Just like a normal number↵
so the ID would be ABC = 26^2*1 + 26^1 * 2 + 26^3 * 0. ↵
↵
I did this in C++ and my code is above. It passes all but 3 test cases. And these are very close to the cut off of BRUTMHYHIIZP = 10^16, and my answer and the output differ by 1. ↵
↵
Is this because of the pow() function that I used? Or am I just wrong? ↵
↵
P.s: I read the atcoder editorial and they "initialise" by 26^1 + 26^2 .... 26^l-1. where l is the length of the string and then go on to just count where along the list the specific string is and then add it to the sum above so I know we did it different ways (sort of).↵
↵
I just don't know why mine is wrong. I've spent a lot of time on it, and even tried using round(pow()) but I don't know why it's still wrong↵
