### Test Suite

Test Status Code Input and Output
1   Pass
filetext = fileread('oddEven.m'); assert(isempty(strfind(filetext, 'regexp')),'regexp hacks are forbidden')

2   Pass
filetext = fileread('oddEven.m'); loopUsed = any(strfind(filetext, 'while')) || any(strfind(filetext, 'for')); assert(~loopUsed, 'Loops are forbidden')

3   Pass
v = []; w_correct = []; assert(isequal(oddEven(v),w_correct))

4   Fail
v = [2; 7; 0; 3; 2]; w_correct = [7; 3; 2; 0; 2]; assert(isequal(oddEven(v),w_correct))

Array indices must be positive integers or logical values. Error in oddEven (line 2) w = [v(mod(v,2))==1 v(mod(v,2))==0]; Error in Test4 (line 3) assert(isequal(oddEven(v),w_correct))

5   Fail
v = [1, 0, 2, 9, 3, 8, 8, 4]; w_correct = [1, 9, 3, 0, 2, 8, 8, 4]; assert(isequal(oddEven(v),w_correct))

Array indices must be positive integers or logical values. Error in oddEven (line 2) w = [v(mod(v,2))==1 v(mod(v,2))==0]; Error in Test5 (line 3) assert(isequal(oddEven(v),w_correct))

6   Fail
odd = 2 * randi([-4, 4], 1, randi([4,10])) - 1; even = 2 * randi([-4, 4], 1, randi([4,10])); v = [even, odd]; w_correct = [odd, even]; assert(isequal(oddEven(v),w_correct))

Array indices must be positive integers or logical values. Error in oddEven (line 2) w = [v(mod(v,2))==1 v(mod(v,2))==0]; Error in Test6 (line 5) assert(isequal(oddEven(v),w_correct))
