Added test findDigit(-456, 4) to all languages (expecting 0).

The negative part is ignored and the number '4' has been declared. Since it says to count from right to left, we had to add a zero on the left side to accommodate for the nth value. So -456 become 0456. Therefore, 0 is the correct answer for the 4th position.

Change to:

fn find_digit(num: i32, nth: i32) -> i32 {
   // 
}

In Rust nth is declared as usize but negative numbers are passed.

Why findDigit(-456, 4) value is return 0?

I've done about 5 Katas in my own IDE that run fine but everytime i try on this website i get EOF errors. What am i doing wrong

in Python quite some solutions would have a problem with the test below cause they ignor the case hiting the "-" at negative numbers pls add or corect me if I misunderstood the kata
Test.assert_equals(find_digit(-5540, 5), 0)
