The code above means to randomly pick a number from 1 to 7 and then pick 6 without duplication. The problem is the break after else; if you add it, it is wrong. If you don’t add it, it is right. In my understanding, break means jumping out of the current loop. Meaning: So when it is found that the number is not repeated, assign a value and then jump out of the loop and go to the next loop. However, if brake is added, duplicate arrays will appear. I don’t know the application of break very well
