Let's Plant Rice Problem Submissions To simulate rice paddy maintenance, a game company decided to use the following function to calculate the evaporation rate of water: rate=1-(- Discussions -)" + d 1+e (0.5) Where: •-how full the rice paddy is at the start of the day, the value of which ranges from 0.0 (0% water level) to 1.0 (100% water level) •d, k, and a-variables that control the rate of evaporation. When a rice paddy is filled with water, the evaporation rate is set for that day, and water would slowly evaporate following this rate. Upon releasing the game, players discovered that if a sweet spot evaporation rate a, with an error margin of 0.1 is used, the water level would be perfect every time and would result in the best quality crop. However, because players were not yet aware of factors d, k and a, they were unable to figure out how to properly set their starting water level to exploit this sweet spot. OSN≤5-10³ 05.51 -0.5 ≤ ≤ 0.5 0≤a,k≤5 After data mining through the game, however, you managed to uncover factors d, k, and a, and you found our that these three factors were arbitrarily set at the start of each day. Moreover, there are indeed days where, no matter what you set your starting water level to, the sweet spot cannot be reached (darn those cheeky game developers). Your task is to write a program that, given the values of d, k, and a, would determine the starting water level that would result in an evaporation rate of for that particular day. On days where a cannot be reached, indicate that "Sweet spot cannot be reached! Those cheeky developers!". Input Format The first line of the input contains an integer N, indicating the number of days you would need to figure out the starting water level for. N lines follow, each containing four space-separated real numbers that correspond to the value of a, d, k, and a.a is the sweet spot evaporation rate. d, k, and a are described in the problem statement.
