Problem 1451. Symmetry of vector

Created by Selvaraaju Murugesan

Solve Later

Determine whether the vector is symmetric or not (vector could be even or odd in length).

For example:

 x = [1 2 3 3 2 1] is symmetric

 x = [1 2 3 4 3 2 1] is symmetric as well!

 x = [-1 -2 -3 3 2 1] is not symmetric

Case #3 is not symmetric...please check.

I fixed the wording.

Why the vector from "Test Suite" "Test 3" is symmetric?

x = [-1 0 0 1];
y_correct = 1; %% WHY 1?

I updated test case #3.

Include a test case where first and last are same, but ones in middle aren't (say [1 2 4 3 5 2 1])

What if you update the test #3 in test suite?
