Sorting Algorithm - 2 (Shaker Sort)

A slightly improved version of BUBBLE SORTING.


void shaker_sort(char *str,int count)
{
int i,exchange=0;
do{
exchange = 0;
for(i=1;i<count-1;i++)
{
if(str[i]>str[i+1])
{
exchange = 1;
swap_items(&str[i],&str[i+1]);
}
}
for(i=count-1;i>0;i--)
{
if(str[i-1]>str[i])
{
exchange = 1;
swap_items(&str[i-1],&str[i]);
}
}
}while(exchange);
}
void swap_items(char *a,char *b)
{
(*a)^=(*b)^=(*a)^=(*b);
}
