There are 100 people and 100 boxes. Each person has three votes with ranking (first choice, second choice, third choice). With each voice, the person can choose a different box. For example, person A chooses box 55 with the first voice, box 1 with the second and box 10 with the third. Person B chooses box 45 with the first voice, box 55 with the second and box 5 with the third… It is not possible to choose the same box twice. A box can be selected by several people.
Thanks in advance
