Problem with the code, please explain?

I think your logic is wrong here. When the element from the upper array is same as ideal array, remove it. else you pop it, and put it at the end. What you are doing is you are popping and putting it back but then you are removing all of the characters in between. Please notice that the order in which elements are finally removed from the array has to be in ideal order.
