Section B: Write T for True and F for False Statements
- An algorithm should have 1 or more well-defined inputs. → T
- Flowchart is a graphical method of designing programs. → T
- Algorithms are used for calculation and data processing only. → F
- In a Flowchart, a circle symbol indicates that the flow continues on another page. → T
- Flowchart provides clarity of relationships among various processing steps. → T
Section B: Write T for True and F for False Statements
- The extension of Python files is .pn → F (Correct extension is .py)
- Python can be used to build Artificial Intelligence Algorithms. → T
- The result of
not(8<10 and 22<20)
is True. → T- Explanation:
8 < 10
is True,22 < 20
is False →True and False
is False.
Applyingnot(False)
, we get True.
- Explanation:
- for loop allows a part of the code to be repeated unlimited number of times. → F (It runs for a specified range or until a condition is met.)
- The input
12345
returns "not a palindrome." → T (Since12345
is not the same when reversed.)
