Problem 1035. Generate a vector like 1,2,2,3,3,3,4,4,4,4
Generate a vector like 1,2,2,3,3,3,4,4,4,4
So if n = 3, then return
[1 2 2 3 3 3]
And if n = 5, then return
[1 2 2 3 3 3 4 4 4 4 5 5 5 5 5]

With the usage of for loops this becomes doable. There are similar problems where it (and while) are explicitly banned in test cases so that my solution there got errored. How do I solve this without?

@Long Runjia Yu Perhaps look at other (correct) solutions to this problem, and learn from them.
Here (and elsewhere) one way to solve the problem at hand is to generate more than you need, and then throw away that which is superfluous (both without loops).
