Moving Zeros to end: Given an array of n integers, move all the zeros of a given array to the end of the array. gfg code example

Example: Move all zeros present in an array to the end

def swap(A, i, j):
 
    temp = A[i]
    A[i] = A[j]
    A[j] = temp
 
 
# Function to move all zeros present in a list to the end
def partition(A):
 
    j = 0
 
    # each time we encounter a non-zero, `j` is incremented, and
    # the element is placed before the pivot
    for i in range(len(A)):
        if A[i]:            # pivot is 0
            swap(A, i, j)
            j = j + 1
