Google CodeJam – Mushroom Monster

Question URL is https://code.google.com/codejam/contest/4224486/dashboard

This question could be become two sub question.
1. less mushroom to eat.
for array 10 5 15 5, what is the sum of decreased numbers?
10 is decreased to 5, the decreased number is (10-5).
5 raises to 15, it will be ignored.
15 is decreased to 5, the decreased number is (15-5)

the sum of all decreased numbers that is (10-5)+(15-5) will be the answer.

2. eating mushroom in static speed.

find the max gap of decreased numbers. (15-5) is the max speed in 10 seconds.
there for, if mushroom number on the dish is greater than (15-5), Kaylin only eats(15-5).

if mushroom number on the dish is less that (15-5), Kaylin will finish all of them and waiting for next refill.

Here is Clang code.
