-        Task
-
-        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 certain level.
-
-        Example
-
-        For upSpeed = 100, downSpeed = 10 and desiredHeight = 910,
-        the output should be 10.
-
-        For upSpeed = 10, downSpeed = 9 and desiredHeight = 4,
-        the output should be 1. Because the plant reach to the desired
-        height at day 1(10 meters).
-
-        Input/Output
+        Testing growing_plant function.
 
-        [input] integer upSpeed
-        A positive integer representing the daily growth.
-        Constraints: 5 ≤ upSpeed ≤ 100.
-
-        [input] integer downSpeed
-        A positive integer representing the nightly decline.
-        Constraints: 2 ≤ downSpeed < upSpeed.
-
-        [input] integer desiredHeight
-        A positive integer representing the threshold.
-        Constraints: 4 ≤ desiredHeight ≤ 1000.
-
-        [output] an integer
-
-        The number of days that it will take for the plant to
-        reach/pass desiredHeight (including the last day in the
-        total count).
