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

lv = 9 7 rv = 9 7 lv = 7 rv = 9 s = 16

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

lv = 1 2 3 4 5 6 7 8 9 10 rv = 1 2 3 4 5 6 7 8 9 10 lv = 2 3 4 5 6 7 8 9 10 rv = 1 2 3 4 5 6 7 8 9 s = 3 5 7 9 11 13 15 17 19

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