The tortoise can ride an electric car and build a charging station on the road. Each charging consumes t time. After each charging, he can ride a c distance.
Idea: DP can not just look at the status of the I-1 charging station, because it may be in the previous (0-i-1) charging station directly charged directly to the current site. therefore, you need to rescan each charging station.
DP [I] indicates the minimum time used to arrive at the I site.
has never been idle and has not stopped!
So if we want B to catch up with A, we must satisfy this equation:
V1 * time + g = v2 * time
In this way, time is easy, but the most important thing is how to split the time into minutes and seconds.
My approach is to calculate the clock first, and then the minute based on the remainder, and then the second based on the remainder.
function race(v1, v2, g) { var h = -1; var mn = -1; var s = -1; var remainder; var speedGap = v2 - v

Question: Chinese, not explained.
Train of Thought: divide the length of L into n + 2 segments: 0, P [1], p [2]…, P [N], L.
DP [I] is the minimum time from tortoise to segment I,
Turtles can have 0 ~ The I-1 segment selects the minimum time to arrive at I after charging and then classifies it for discussion.

HDU 2059 Tortoise and rabbit race (DP)
Given a rule to ask the result of a race, the question is when the tortoise chooses to charge.
Solution: because there are only 100 charging stations at most, the decision affecting the result takes place in each charging station. Therefore, you only need to consider the strategy to be adopted when arriving at the charging station. You only need to retain the optimal value for a certain station and charge it.
The Code is as follows:
