I want to find out which numbers among them add up to 171780
Requirement: If there are multiple combinations, list them in turn; each number in these 72 numbers in each combination can only be used once.

I don't care about efficiency, nor do I care whether to use third-party tools like awk, etc., as long as the requirement is met.

This is so troublesome with p, and I definitely can't figure it out at my current level, heh. Looking forward to experts' solutions!

Add the first data to the subsequent ones one by one, and discard the first number when reaching the second one...

It should be. To find all combinations, and finally display the combination whose value equals the desired value.

It's a very interesting question, but it seems the difficulty is not small either.

Refer to this and add "if "Calculation result" == "171780" " for judgment at an appropriate place

Find the sum of all different combinations of a column of numbers

72 numbers permutation and combination?

I'm afraid it would take N hours to get the result.

Batch processing doesn't have this computing power yet

I tried that, but nothing came out after a long time. I'm thinking about using VBS or something like that.
