Add test vector a = -12;
b = [1,3,4,5,6,7,8,-12,2]; and rescore.
Better is add a=-randi(16); b= [1 2 3 a];
These will eliminate answers like #6.
Tests allow incorrect solution to pass:
function y = existsInVector(a,b)
y=0
for i = 1:numel(b);
if i==a
y=1
break
end
end
end
good
that was fun, took me a couple minutes
y = sum(b == a);
Not too bad
yay
