+> 🚨 The use of Yul to read and write arrays is not advised. It is a very tricky business, considering the fact that small types are packed and large types occupy one slot, it is a whole new level of stress to take in packing, and other considerations while storing values into an array from Yul. Allow Solidity to handle the intricacies for you.
