Use counting Sorting Algorithm...i am givin the code below ..it sort
the array in O(n) but uses xtra memory space (n+k)...we have to pay
eother memory or time....
#include <stdlib.h>
#include<stdio.h>
#include<conio.h>
int main()
{
int array[]={4,2,2,2,4,5,9,5,10};
int size=10;
int min,max;
max=min=array[0];
int i=0;
//clrscr();
for(i = 1; i < size; i++)
{
if (array[i] < min)
min = array[i];
else if (array[i] > max)
max = array[i];
}
int range = max - min + 1;
int *count =(int *) malloc(range * sizeof(int));
for(i = 0; i < size; i++)
count[i] = 0;
for(i = 0; i < size; i++)
count[array[i]]++;
int pos=0;
for(i=0;i<size;i++)
{
for(int j=0;j<count[i];j++)
{
array[pos]=i;
pos++;
}
}
//free(count);
for(int i=0;i<size;i++)
printf("%d \n" ,array[i]);
getch();
}
