None
PROBLEM:
You buy N cakes, each with a cost of 100.
However, if you buy at least 5 cakes, each one costs only 85 instead.
How much did you spend?
EXPLANATION:
If N \lt 5, each cake costs 100 rupees.
So, the total cost is 100\cdot N rupees.
If N \ge 5 instead, each cake costs only 85 rupees.
So, the total cost is 85\cdot N rupees in this case.
TIME COMPLEXITY:
\mathcal{O}(1) per testcase.
CODE:
Editorialist's code (PyPy3)
