Problem
A cinema charges by age: children under 3 are free, ages 3–12 pay 5, ages 13–64 pay 12, and 65 or older pay 7.
Implement ticket_price(age).
Input
age: The visitor's age in years.
Output
Return the ticket price.
Constraints
0 ≤ age ≤ 120
Examples
Example 1
Input:
age = 10
Expected output:
expected = 5Input:
long long age = 10;
Expected output:
long long expected = 5;Input:
long age = 10;
Expected output:
long expected = 5;Explanation
10 is between 3 and 12, so the price is 5.
Example 2
Input:
age = 70
Expected output:
expected = 7Input:
long long age = 70;
Expected output:
long long expected = 7;Input:
long age = 70;
Expected output:
long expected = 7;Explanation
70 is 65 or older, so the senior price of 7 applies.
How to approach it
Try on your own first, then open one hint at a time.
Hint 1
The price depends on which age band the visitor falls into.
Hint 2
Check the youngest and oldest special cases before the middle ranges.
Hint 3
Pay attention to the exact endpoints so ages 3, 13, and 65 get the correct prices.
Expected complexity
O(1) time, O(1) extra space
