PROBLEM:
A customer buys a cake for X rupees.
If the cost is at least 200 rupees, a cashback of 50 is given.
What’s the effective cost to the customer?
EXPLANATION:
If X \lt 200, there’s no cashback and so the effective price is just X.
If X \ge 200, there’s a cashback of 50 rupees, so the effective price is (X - 50) instead.
Both cases can be checked using an if statement.
TIME COMPLEXITY:
\mathcal{O}(1) per testcase.
CODE:
Editorialist's code (PyPy3)
x = int(input())
if x < 200: print(x)
else: print(x - 50)
