Capeta is working part-time for an animal shipping company. He needs to pick up animals from various zoos and drop them to other zoos. The company ships four kinds of animals: elephants, dogs, cats, and mice.
There are zoos, numbered to . Also, there are animals. For each animal , Capeta knows its type (E for elephant, D for dog, C for cat and M for mouse), source zoo where Capeta has to pick it up from, and destination zoo where Capeta needs to deliver it to.
Capeta is given a truck with a huge capacity where animals can easily fit. He is also given additional instructions:
He must visit the zoos in increasing order. He also cannot skip zoos.
Dogs are scared of elephants, so he is not allowed to bring them together at the same time.
- Cats are scared of dogs, so he is not allowed to bring them together at the same time.
- Mice are scared of cats, so he is not allowed to bring them together at the same time.
- Elephants are scared of mice, so he is not allowed to bring them together at the same time.
Also, loading and unloading animals are complicated, so once an animal is loaded onto the truck, that animal will only be unloaded at its destination.
Because of these reasons, Capeta might not be able to transport all animals. He will need to ignore some animals. Which ones? The company decided to leave that decision for Capeta. He is asked to prepare a report and present it at a board meeting of the company.
Capeta needs to report the minimum number of zoos that must be reached so that she is able to transport animals, for each from to .
Complete the function minimumZooNumbers and return an integer array where the integer is the minimum number of zoos that Capeta needs to reach so that she is able to transport animals, or if it is impossible to transport animals.
He is good at driving, but not so much at planning. Hence, he needs your help.
