This exercise is already present (palindrome) in the piscine - I wouldn't use the same exercises for exam and piscine. If this is the case, there is no need to create a new subject
yes but there is a small difference between the two in the exam they shouldn't provide the solution inside a folder and i see is better to separate between the piscine exercises and the exam exercises
