Take a closer look at your loop declaration.

for (int i = 0; i           >                    5; i++)

No wonder that your beans! are missing from the log I guess. (> != <)

Read this, see if it helps.

No, it says at index 1, it expected a 1 and found a 0, there can be more differences, but that's the first one.

You can print the input.

Expected: equal to [ cod, code, ewar, wars ], Actual: [ cod, code, wars, ewar ]

The description says: "return a sorted array in lexicographical order".
