Implement
Selection Sort Recursively
#include
#include
void selection(int [], int, int, int, int);
int main()
{
int list[30], size, temp, i, j;
clrscr();
printf("Enter the size of the list: ");
scanf("%d", &size);
printf("Enter the elements in list:\n");
for (i = 0; i < size; i++)
{
scanf("%d", &list[i]);
}
selection(list, 0, 0, size, 1);
printf("The sorted list in ascending order is\n");
for (i = 0; i < size; i++)
{
printf("%d ", list[i]);
}
return 0;
}
void selection(int list[], int i, int j, int size, int flag)
{
int temp;
if (i < size - 1)
{
if (flag)
{
j = i + 1;
}
if (j < size)
{
if (list[i] > list[j])
{
temp = list[i];
list[i] = list[j];
list[j] = temp;
}
selection(list, i, j + 1, size, 0);
}
selection(list, i + 1, 0, size, 1);
}
getch();
}
Output
Enter the size of the list: 5
Enter the elements in list:
23
45
64
12
34
The sorted list in ascending order is
12 23 34 45 64
Input Few Numbers & Perform Merge Sort on them using Recursion
#include
#include
void mergeSort(int [], int, int, int);
void partition(int [],int, int);
int main()
{
int list[50];
int i, size;
clrscr();
printf("Enter total number of elements:");
scanf("%d", &size);
printf("Enter the elements:\n");
for(i = 0; i < size; i++)
{
scanf("%d", &list[i]);
}
partition(list, 0, size - 1);
printf("After merge sort:\n");
for(i = 0;i < size; i++)
{
printf("%d ",list[i]);
}
return 0;
}
void partition(int list[],int low,int high)
{
int mid;
if(low < high)
{
mid = (low + high) / 2;
partition(list, low, mid);
partition(list, mid + 1, high);
mergeSort(list, low, mid, high);
}
}
void mergeSort(int list[],int low,int mid,int high)
{
int i, mi, k, lo, temp[50];
lo = low;
i = low;
mi = mid + 1;
while ((lo <= mid) && (mi <= high))
{
if (list[lo] <= list[mi])
{
temp[i] = list[lo];
lo++;
}
else
{
temp[i] = list[mi];
mi++;
}
i++;
}
if (lo > mid)
{
for (k = mi; k <= high; k++)
{
temp[i] = list[k];
i++;
}
}
else
{
for (k = lo; k <= mid; k++)
{
temp[i] = list[k];
i++;
}
}
for (k = low; k <= high; k++)
{
list[k] = temp[k];
}
}
Output
Enter total number of elements:5
Enter the elements:
12
36
22
76
54
After merge sort:
12 22 36 54 76
