How to draw out all the hearts in a deck of playing cards?

First judge whether the number of towers is odd or even.

2

Remember the formula, odd number to the left, even number to the right.

three

Keep an eye on the top of the tower The first step is to move it to the left or right according to the above odd left even right principle.

four

After moving, you can't operate this small tower in the next step, you can only take any other step (in fact, only one step is legal).

five

Keep your eyes on the small tower and move in the same way according to the original odd left and even right principle (that is, it moved left or right originally, and this time it moved left or right).

six

As in step 4, do not operate the small tower, and take any other steps (in fact, only one step is legal).

seven

Cyclic operation will eventually move the whole tower to the far right.
