Aracade Intro #38 growingPlant. Algorithm, 알고리즘, Codefights, CodeSignal, 코드파이트, 코드시그널, 예제, example, c++ java c# scalar
Aracade Intro #38 growingPlant. Algorithm, 알고리즘, Codefights, CodeSignal, 코드파이트, 코드시그널, 예제, example, c++ java c# scalar Q. Each day a plant is growing by upSpeed meters. Each night that plant's height decreases by downSpeed meters due to the lack of sun heat. Initially, plant is 0 meters tall. We plant the seed at the beginning of a day. We want to know when the height of the plant will reach a c..
