Create a function that finds the largest palindromic number made from the product of at least 2 of the given arguments.

I already told you how you get the number, it's not using all the arguments. See the last example.

Result should be made from nums of the product or it should any number be up to the product?

But there is no "8"s in 451165470, or maybe I misunderstood the kata

8510158 is greater than 5417145, isn't it?

7 * 23 * 87 * 32210 = 451165470, you missed 87

Why do you think it's an error?

7 * 23 * 32210 = 5185810 and that can be rearranged to 8510158 there is no error.

I think there are errors in tests:
Testing for 7, 23, 87, 32210 -> expected 5417145 to equal 8510158

Guys, we read carefully: a product of any number of arguments!

Ruby 3.0 should be enabled.

Very clever edge cases!

Nice kata but the two different tasks are not really related...

These incorrect Python solutions fail at the random tests sometimes, but pass all the fixed tests. Fixed tests for those cases should be added.

You can print input to debug, or read 4th note.
Anw, this is not an issue.

I keep timing out :(

My script executes in 86ms on an online Python interpreter with this input (937,113,4782,1,456,0,24,7824,13,6985).
Seems quite efficient to me.

What kind of test is taking so long ?
How can I find it ?

You can't use the same number more than once.
3534 only has one 5 but 535 has two 5s
