Hello,

I was trying to solve 383E - Vowels. Using the technique described here: https://mirror.codeforces.com/blog/entry/45223

I managed to get AC here: 61233188 using regular memory reduction (Reducing one of the dimensions to the size of 2).
I don't understand how it can be reduced to one-dimensional like this: 61233599.

Here is an image to demonstrate my understanding of the dp dependencies in this problem:
