Move Zeros

Given an array of integers, move all the 0s to the back of the array while maintaining the relative order of the non-zero elements. Do this in-place using constant auxiliary space.


1[1, 0, 2, 0, 0, 7]


1[1, 2, 7, 0, 0, 0]

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.

Contrary to popular belief, Lorem Ipsum is not simply random text.

1  >>> a = [1, 2, 3]
2  >>> a[-1]
3  3
