x is a vector with numbers of pizza slices. A corresponding vector n indicates in how many slices the pizza slices of x were cut and t is a vector indicating the type of pizza (e.g. 1 is a margarita, 2 is a peperoni, etc.). How many complete pizzas do we have, when we cannot join 2 different pizzas?

Example:

 x = [1 3 12];
 n = [2 6 8];
 t = [1 2 1];

in the first column we have on slice (x=1) from a pizza margarita (t=1) cut in half (n=2) -> half a pizza margarita. in the second column we have 3 slices (x=3) from a peperoni pizza (t=2) cut in 6 slices (n=6) -> so half a peperoni pizza. in the third column we have 12 slices of a margarita pizzas (t=1) cut in 8 slices ->1.5 slices margarita pizza.

so we can combine this to 2 pizza margaritas and 0.5 peperoni pizza. So in total we can combine 2 pizzas.
