The length of the data to manipulate:
If there are registers on either side of the operator, the size of the register determines whether the operation is a word or a byte.
If there is no register, you can specify it yourself:
mov word ptr [2],1
mov byte ptr [2],1
Some designations specify whether the access is a word or a byte by default:
div means
()-start);

As you can see, the greater the N value, the more obvious the advantage of using caching calculations. As an exercise, you can try to modify the function of calculating the factorial yourself.
