Opgave

Swipe to start coding

You have such a string programming. You have to carry out these steps:

  1. print elements sliced till 8th element from last(as a result you have to get: pro)
  2. print elements sliced from index -8 to -3(as a result you have to get: grammi)
  3. print elements in reverse using slice operation(as a result you have to get: gnimmargorp).
