Rewrite the following SQL statement after correcting the error(s). Underline the corrections made.

INSERT IN STUDENT (RNO, MARKS)   
VALUE (5, 78.5);

Write a function Push() which takes number as argument and add in a stack "MyValue".

Expand the following:

(a) LIFO

(b) FIFO

Assertion (A): Program should check for Overflow condition before executing Push operation on stack and similarly check for Underflow condition before executing Pop operation.

Reasoning (R): In stack, Underflow condition signifies that there is no element available in the stack while Overflow condition means no further element can be pushed in the stack.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.
