I came with same solution✌️

[@techdose4u]

✌🏼

[@maheshgnayak5721]

I did the same. ie 4*(np2) using factorial, but one large test case was failing. Maybe it was going above Integer value? But didn't get error saying integer overflow, so couldn't debug.

Hello, if I don't know about the math equation about Nc2? 1) How do I recognize to use this in an interview? 2) Do you recommend to memorize some common math patterns? 4) Is there a list of those Math tricks? Or use a non math way of solving it?

[@techdose4u]

No there is memorization of this.
Nc2 is something expected from everyone to know.
But, in order to recognize this, you need to take a notebook and write answers for your test cases in increasing order and see if it makes any pattern. This will be best.

[@watchmovies5854]

I thought of taking lcm

[@techdose4u]

😮
