# Move zeroes

# Move zeroes

Sequence of numbers is given. Move all **0**'s to the end of it while maintaining the relative order of non-zero elements.

#### Input

First line contains number of elements **n** (**1** ≤ **n** ≤ **100**) in the sequence. Second line contains **n** integers, not greater than **100** by absolute value.

#### Output

Print the sequence so that all its **0**'s are moved to the end, and the relative order of non-zero elements is not changed.
