im sorry this was my first kata im trying to make it better thanks for reporting issues

There are already several existing katas about this exact type of DP.

It is not specified what should happen if it is not possible to form x using the available coins (e.g x = 5, coins = {2, 4}), or if they would happen at all.

Also:

A vector of integers coins (1 ≤ coins ≤ 100) representing different coin denominations available.

The range of elements of coins should be specified too. What if 0 or negative numbers appear in coins?

Sample tests doesn't work:

In file included from main.cpp:7:
./tests.cpp:10:2: error: expected ';' after struct
}
 ^
 ;
1 error generated.

There are no random tests either.

what is going on its just a sum mate

im just mad
