The function which cause side effects to the arguments passed are called __________.
a.
Dynamic function
b.
Impure function
Correct Answer
c.
Pure function
d.
Partial function
Step-by-Step AI Explanation
Verified Method
The correct answer is (b) Impure function. An impure function may produce side effects or depend on external state, so the result is not determined only by its input arguments. A pure function, on the other hand, does not cause side effects and always gives the same output for the same inputs.

The datatype whose representation is known are called __________.
a.
Concrete datatype
Correct Answer
b.
Built in datatype
c.
Abstract datatype

Secured members
b.
Public members
Correct Answer
c.
Private members
d.
Protected members

Two main measures for the efficiency of an algorithm are __________.
a.
Time and Space
Correct Answer
b.
Processor and Memory
c.
Complexity and Time
d.
Data and Space
Step-by-Step AI Explanation
Verified Method
The correct answer is (a) Time and Space. The efficiency of an algorithm is mainly measured by its time complexity and space complexity. Time measures how long the algorithm takes, and space measures the memory used.

Which of the following is the output of the given Python code if the value of $a$ is 52 ?
x='even' if $a\%2==0$ else 'odd'
print(x)
a.
error
b.
even
Correct Answer
c.
no output
d.
odd
Step-by-Step AI Explanation
Verified Method
The correct answer is (b) even. Since $a = 52$, the condition $a\%2==0$ is true because 52 is divisible by 2. So the expression assigns 'even' to x, and print(x) displays even.

If mylist=[10, 20, 30, 40] then mylist.append(35) will result :
a.
[10, 35, 20, 30, 40]
b.
[10, 20, 30, 40, 35]
Correct Answer
c.
[35, 10, 20, 30, 40]
d.
[10, 20, 30, 35, 40]
Step-by-Step AI Explanation
Verified Method
The correct answer is (b) [10, 20, 30, 40, 35]. In Python, append(35) adds the new element to the end of the list. It does not insert it in the middle or remove any existing element.

a.
$$num
b.
__num
Correct Answer
c.
++num
d.
##num
Step-by-Step AI Explanation
