Brain teasers super hard .

I don't understand the expression too well, so please refer to the following.

Three pairs of tiger mothers and children have to cross the river (A, A is mother and child, B and B are mother and child, C and C are mother and child), and there is only one boat;

The boat can carry up to two tigers at a time (no limit on large or small tigers);

The three big tigers (A, B, C) can sail, and only A of the three small tigers (A, B, C) can sail;

Note: 1. If the baby tiger leaves its mother, it will be eaten by other big tigers who are with it (e.g., on the same side of the river or on the same boat, etc.)!

2. Three big tigers (a, b, c) can coexist peacefully, and three small tigers (a, b, c) can also coexist peacefully.

Q: How did the three pairs of tigers cross the river safely?

There is only one boat, and each boat is limited to two tiger .........All only, and every one?

I didn't understand it too much, so it's okay to let a mother and son be together at a time.

It's this again. It's simple, just follow the facts.

I don't understand what you said, but the 3L one is right, you can refer to it.

It's not super hard, it's super bad.

It's stupid, it's stupid, no matter what, it's going to be 2 small and 1 female or 2 female and 1 small.
