Problem 57939. Sequence Vectorization - II
This is the second part to the question - Sequence Vectorization - I
Given an array of Natural numbers, N, return the sequence - horizontal concatenation of (1:k) for k - N(1), N(2), ... N(end)
%Example 1
N=[2 5 3];
Out=[1 2, 1 2 3 4 5, 1 2 3];
%Example 2
N=[3 4];
Out=[1 2 3, 1 2 3 4];
%Example 2
N=[11 1 5];
Out=[1 2 3 4 5 6 7 8 9 10 11, 1, 1 2 3 4 5];
As the question deals with vectors, the solutions must be vectorized as well. Check the test suite for banned functions.

Am I missing something?
In test 7, there is a sequence 1:7 that seems to come out of nowhere.
Also, in test 10, there are 2 issues: 1) line 3 is missing a parenthesis, and 2) the array t has only 25 elements, but is evaluated for a random index between 1 and 100.

Apologies William, the reference answer to test case #7 was incorrect and as you mentioned test case #10 had issues.
I have corrected the errors, and your solution has been rescored. Please rate the question!
