Answer:
The function is as follows
public static void pushZero(int[] A){
int curr = A.length - 1;
for (int i = A.length - 1; i >= 0; i--) {
if (A[i] != 0) {
A[curr] = A[i];
curr--;
} }
while (curr >= 0) {
A[curr] = 0;
curr--; }
for (int i = 0; i < A.length; i++) {
System.out.print(A[i] + " ");
} }

Write a function to move all 0s to the beginning of the array
The function is defined here
public static void pushZero(int[] A){
This sets the current element to the last element
int curr = A.length - 1;
This for loop through the array backwards
for (int i = A.length - 1; i >= 0; i--) {
This condition checks if the current element is not 0
if (A[i] != 0) {
Set the current element to the current iterating element of the array
A[curr] = A[i];
curr--;
} }
This while iteration is repeated while the current element is greater than 0
while (curr >= 0) {
Set current element to 0
A[curr] = 0;
curr--; }
The following for loop prints the sorted array
for (int i = 0; i < A.length; i++) {
System.out.print(A[i] + " ");
} }
