Programming Logic & Test Strategy
Question: What is a common "shortcut" or "tip" to pass a specific test case in an
auto-graded programming assignment if you are struggling with the logic?
Answer: print("insert expected output") > AI Note: This is often called "hard-
coding." While it might get you points for a specific test case by matching the
expected string exactly, it doesn't solve the actual problem logic and usually fails
when the hidden test cases use different input values. Use it only as a last resort to
diagnose formatting!
Question: How do you write a Python solution that calculates the square root of a
float input, formats it to two decimal places, and then determines if the original
input is a perfect square? Answer: ```python import math
Input: Get the number from the user
square_root_input = float(input())
Process: Calculate the square root
x = math.sqrt(square_root_input)
Output the square root formatted to two decimal places
print(f'{x:.2f}')
Logic: Check if it's a perfect square using the remainder (modulo) operator
If the original number divided by its root has no remainder, it's a perfect
square
remainder = square_root_input % x
if remainder == 0: print('True') else: print('False')
