Problem 51813. Sum the elements in rows of the Levine triangle
The Levine triangle starts as follows:
Row 0: 2
Row 1: 1 1
Row 2: 1 2
Row 3: 1 1 2
To construct each row, read the previous from the right. Row 0 tells us to put two 1s in row 1. Row 1 tells us to put one 1 and one 2 in row 2. Row 2 tells us to put two 1s and one 2 in row 3. Et cetera.
Write a function that computes the sum of the elements in the nth row of the Levine triangle and reports the sum as a string. Codes that can handle the optional tests will earn ten (10) Chris R. Appreciation Points.

My code choked on n = 12 on my laptop. That was the motivation for the three optional tests, as well as for one of the tags.

Disallowing 'if' seems to disallow 'circshift' also, which I assume was not your intent.

Correct. I changed the test to look for 'if '.
