2   Fail
v = randi(10, 1, randi(10)); s = summ(v); assert(length(s) == length(v) - 1)

s = 13 11 14 15 11 5 3 8 9

Assertion failed.

3   Fail
v = 1:10; s_correct = 3:2:19; assert(isequal(summ(v),s_correct))

s = 3 5 7 9 11 13 15 17 19

Assertion failed.

4   Fail
v = [1; 2; 4; 4; 5; 8]; s_correct = [3; 6; 8; 9; 13]; assert(isequal(summ(v),s_correct))
