We need to do these 3 things:

1. Separate the 0s and non-0s.
2. Find out where the non-0s need to be index-wise
3. Keeping track of the number of 0s

We have a potential brute force solution! This could be our pseudocode.

xxxxxxxxxx

temp = []

zero_count = 0

iterate through array:

  if nonzero, push to new temp

  if zero, increment count

for zero_count times:

  push to temp

return temp
