  4.Write a program to sort a list of N elements using Selection Sort Technique   
  
     #include < stdio.h>

int main()
{
    int a[100], n, i, j, min, temp;

    printf("Enter the number of elements: ");
    scanf("%d", &n);

    printf("Enter %d elements:\n", n);
    for(i = 0; i < n; i++)
        scanf("%d", &a[i]);

    for(i = 0; i < n - 1; i++)
    {
        min = i;

        for(j = i + 1; j < n; j++)
        {
            if(a[j] < a[min])
                min = j;
        }

        temp = a[i];
        a[i] = a[min];
        a[min] = temp;
    }

    printf("Sorted list in ascending order:\n");
    for(i = 0; i < n; i++)
        printf("%d ", a[i]);

    return 0;
