Question description

This question is a fill-in-the-blank question. You only need to calculate the result and use the output statement in the code to output the filled-in result.

Holmes explores an old castle and sees a strange formula written on the door: ABCDE ∗ ?=EDCBA

He said to Watson: "ABCDE should stand for different numbers, and the question mark should stand for a number!"

Watson: "I guess so!"

So, the two of them were silent for a long time, but still couldn't come up with a suitable result.

Please take advantage of your computer to find the answer to the crack.

Write the numbers represented by ABCDE.
