Q:

Write an algorithm to separate all ones & zeroes in an array.

Answer

1. Have two indexes pointing to two ends of array, say i and j.

2. Approach towards each other with a check condition that they dont cross each other.

3. Each iteration of while loop, swap the numbers pointed by two indexes when num[i] index number is not equal to 1.

void sort()

{

int a[]={1,0,0,0,1,1,0,1,0,1,0,0,1,0};

int i=0;

int j=13;

int temp;

while(j>i)

{

if(a[i]==1)

i++;

if(a[j]==0)

j--;

if(a[i]==0)

{

temp=a[i];

a[i]=a[j];

a[j]=temp;

}

for(i=0;i<14;i++)

Console.Write(a[i]+", ");

}

Output: 1,1,1,1,1,1,0,0,0,0,0,0,0
