and i did a sort :(

just out of curiosity, could you mention how it is messy? the only error i understand is that the code doesn't check the each parameter fully. isn't that the only thing that needs to be corrected?

very tidy solution. Like this

respect

Clever :)

Yeah but this is messy "code" I don't understand how he gets the best practice?

There are 6 code variations, all of them with removed lines

why didn't you remove the last two lines?

how I should know this? any suggestion on complementary material?

noooo, it's substraction, he wants to control the size of the sum..
because when 3 int params are given, they must be in the correct range, so subtraction of any two of them will not cause a overflow.
That should be some kind of tech worthy to remember.

So "rapper" beats "soprano"?

In Visual Studio, this code does not work when ending is longer than str in Debug mode.

Doesn't this read out of bounds (in front of the string) if ending is longer than str?

i don't know how people think this is not best practice but damn this was good solution as compare to me tho
