prev  |  next  |  chance

Goal: Move the negative number to the end of the array. There can be 0 or more negative values. All positive numbers must remain in the same relative order. All negative numbers must remain in the same relative order.

Codingbat doesn't check if you used a 2nd array or modified the original. Please only use the single array, do not make a copy. Return the modified array when you are done.

When debugging think about why adjacent ones fail. Trace out the results. Think about how to skip over numbers that have already been shifted. Take a look at a java visualizer to trace through your code: https://pythontutor.com/java.html#mode=edit

To debug in a java file add the keyword static to your function header: public static int[] moveAllNegativeToEnd(int [] data){


moveAllNegativeToEnd([1]) → [1]
moveAllNegativeToEnd([-1]) → [-1]
moveAllNegativeToEnd([-1, 1, 2]) → [1, 2, -1]

...Save, Compile, Run (ctrl-enter)

public int[] moveAllNegativeToEnd(int [] data){ }
