Given a Natural number N, return the sequence - [1 1 2 1 2 3 1 2 3 4 ... 1 2 3 ... N-3 N-2 N-1 N] i.e. the horizontal concatenation of (1:k) for k=1:N
%Example 1
N=3;
Out=[1, 1 2, 1 2 3];
%Example 2
N=7;
Out=[1, 1 2, 1 2 3, 1 2 3 4, 1 2 3 4 5, 1 2 3 4 5 6, 1 2 3 4 5 6 7];
As the question deals with vectors, the solutions must be vectorized as well. Check the test suite for banned functions.
There will be a second part to this question.

Enjoyed this problem (and liked it). An interesting problem set idea that I haven't seen, but I feel like you could put together: programming problems that must be solved through vectorized solutions to earn a badge. I'm not a vectorizing purist to be clear (and wouldn't encourage that at the potential expense of things like readability), but such problems do force you to think about what tools MATLAB has, and encouraging awareness of those tools is worthwhile.
