Answer:
A and B have different output:
A output will be 1
B output will be 123
Explanation:
A
X = 0
do x < 3
x = x+1
print x
while
B
X = 0
do x = x+ 1
print x
while x < 3
For statement A the condition statement which suppose to be after "while" is not set therefore the value of x will be printed.
For statement B the condition statement is set "x < 3" in front of "while" thereby result in iteration until the condition is false.
Statement A output will be 1
Statement B output will be 123

Explanation:
Five basic set operators in relational algebra are as follows:
- Selection - tuple selection
- Projection - extract columns
- Cartesian product - cross product of relations
- Set union - union of two relations
- Set difference - minus operation on two relations
As we can see, Join is not part of the basic set operations but it is implemented using the Cartesian Product operator.
