Examples:
Input:
arr[ ] = {1, 1, 0, 1, 0, 0, 0, 1, 1, 0}
Output:
arr[ ] = {0, 0, 0, 0, 0, 1, 1, 1, 1, 1}
#include <bits/stdc++.h>
using namespace std;
// function to sorting 0 and 1
void sortFun(int array[], int n)
{
int l = 0;
int r = n - 1;
// loop until l is less than r
while (l < r)
{
if (array[l] == 1)
{
// swap element at l and r
swap(array[l], array[r]);
r--;
}
else
{
l++;
}
}
}
// Function to print the array
void printArray(int array[], int n)
{
for (int i = 0; i < n; i++)
cout << array[i] << " ";
cout << endl;
}
// Main function
int main()
{
int array[100], n;
cout << "Enter Number of elements: ";
cin >> n;
for (int i = 0; i < n; i++)
{
cin >> array[i];
}
// sorting the array
sortFun(array, n);
cout << "Sorted Array" <<endl;
printArray(array, n);
return 0;
}
Output:
Enter Number of elements: 8
1 0 1 0 1 1 0 0
Sorted Array
0 0 0 0 1 1 1 1
