Input is crossing time list. (for example x= [1 2 5 8])
Output is the length of all possible crossing time records. (for original problem y_correct= 14. In other words it is possible to cross the bridge in [15, 17, 18, 19, 21, 22, 24, 25, 27, 28, 30, 31, 34, 40] minutes.
Assumption 1: for this problem only four people will cross the bridge
Assumption 2: crossing times are integer
Crossing Model: 2 out of 4 people will cross the bridge, one of them will return. two out of 3 people will cross the bridge, one out of three people will return. Remaining two people will cross the bridge.

Too many loops and a long solution. But my brain broke down when trying to do it in 4- or 5-dimensional arrays :')
