Answer:
The answer is "Option a".
Explanation:
Privacy is a set of rules, which limiting access to the data, and integrity ensures impartiality, accuracy, and reliability is assured to ensure, which authorized persons can have secure access to the data.
The system needs no access for everyone to achieve its secrecy and integrity contained in a completely safe data system, that's why the given statement is "true".
Answer:
The Update statement in the DML is used for changing existing data in a table.
Explanation:
Their are following Sql statement in the DML.
Insert
This SQL statement is used for inserting data into the table.
select
This SQL statement is used for retrieving data from database
update
This SQL statement is used for updating data in a table.
delete
This SQL statement is used for delete data from database .
The "UPDATE" SQL statement in DML is used for Modify the data in the existing table .
Following are the syntax of Update SQL query
Update tablename
set column1=value1,column2=value2............column N=valueN
Where condition;
Example :Suppose we have student table and (rollno,name,age and add) are the field for that table we have to change the address of rollno 105
Then we use update query like that
UPDATE STUDENT
SET add='kalam nagar'
where rollno=105;

Answer:
O(n) which is a linear space complexity
Explanation:
Space complexity is the amount of memory space needed for a program code to be executed and return results. Space complexity depends on the input space and the auxiliary space used by the algorithm.
The list or array is an integer array of 'n' items, with the memory size 4*n, which is the memory size of an integer multiplied by the number of items in the list. The listSize, i, and arithmeticSum are all integers, the memory space is 4(3) = 12. The return statement passes the content of the arithmetic variable to another variable of space 4.
The total space complexity of the algorithm is "4n + 16" which is a linear space complexity.
