Test Status Code Input and Output
1   Pass
%% x = [1 2 3 4 5 6 7]; xi = split_it(x); assert(isequal(sum(x(xi)),sum(x)/2));

i = 97

2   Pass
%% x = [2 2 2 2 2 2]; xi = split_it(x); assert(isequal(sum(x(xi)),sum(x)/2));

i = 1

3   Pass
%% x = [2 5 4 5 4]; xi = split_it(x); assert(isequal(sum(x(xi)),sum(x)/2));

i = 37

4   Pass
%% x = [1 3 1 1 9 7]; xi = split_it(x); assert(isequal(sum(x(xi)),sum(x)/2));

i = 37

5   Fail
%% x = primes(100); xi = split_it(x); assert(isequal(sum(x(xi)),sum(x)/2));
