sorry i have a question what's the meaning of int and max? got confuse with the computation.
waittime = 360;
if(activity >= 15)
waittime = (int)(90 - activity);
if(activity >= 60)
waittime=(int)(34.7586 - (0.0793103 * activity));
if(activity >= 100)
waittime = max((int)(14-(activity/50)), 4);
(int) means the computation will be converted to an int rather than a float (Ex. 4 instead of 4.1052)
max(value,value) means it'll take the max value between these two numbers
