I have same issue does anyone have resolve that issue ?

bump, I have the same issue, my code seems to be returning exactly what it should but I'm getting the same error.

I have a C++ solution which passes the tests on my machine. When I run it on Codewars, I get the errors:

Single_Word
Expected: equal to emocleW
Actual: emocleW
Mulitple_Words
Expected: equal to Hey wollef sroirraw
Actual: Hey wollef sroirraw

I do not see why my solutions are not validated by the test.

I also have problems with the haskell tests:

pageIndex
should work for some collections and ipp values
Test Passed
should reject invalid indices
Test Passed
should work for random collections and ipp values
Falsifiable (after 2 tests and 1 shrink): 
expected: Just 0
 but got: Nothing
[0]
Positive {getPositive = 1}
-1```
