Answer:
B.O(1)
Explanation:
When we are implementing ADT stack using linked chain we can pop an entry from the stack having O(1) time complexity because in linked chain we have the head or top pointer in linked chain only.Popping and pushing in stack happens on only one end that is top.So we have move to move top in linked chain to the next and delete prev node.
Answer:
columns, rows
Explanation:
In Computer programming, a atabase schema refers to the logical design of the database while the database instance refers to a snapshot of the data found in a database at a given instant in time.
Basically, in database management, the term "schema" is used to denote a representation of data while the term "instance" is used to denote an instance of time.
A database schema is a structure which is typically used to represent the logical design of the database and as such represents how data are stored or organized and the relationships existing in a database management system. There are two (2) main categories of a database schema; physical database schema and logical database schema.
Also, a database instance is a snapshot of the data in the database at a given instant in time and as such represents an operational database by following the conditions, validation and constraints set for a database management system.
These data can be stored or organized in a database management system through the use of multiple-column record formats.
In a multiple-column record of a data file, columns represent different variables and rows represent different cases (respondents) such as experimental data, independent observations etc.
