Apply TodayVery easy, you just have to multiply 2 numbers but you cannot use the following signs (*, /, - ,^) ,mtimes , times, cross, prod, cumprod , dec2bin, int2str and num2str functions. Will you take up the challenge?!

Example : x= 3; y= 2;

output = 6 since 3*2 = 6 :)

It fails because you use the minus sign and there is the following test :
assert(isempty(strfind(filetext, '-')))

Test 1 is always showing Fail. This is disgusting. May be some error on the creator part. Kindly check...

The error for Test 1 says "Output argument 'output' (and maybe others) not assigned". Close examination of your code reveals that when x is 1 and y is 2, you go down the first switch of the outer "if" statement, and sure enough, output never gets assigned and the function fails.
