Output

    Enter total number of elements: 10
    Enter array elements:
    Enter element 1: 12
    Enter element 2: 34
    Enter element 3: 43
    Enter element 4: 32
    Enter element 5: 21
    Enter element 6: 1
    Enter element 7: 11
    Enter element 8: 2
    Enter element 9: 3
    Enter element10: 100
    Array elements in Ascending Order:
    1 2 3 11 12 21 32 34 43 100
    Array elements in Descending Order:
    100 43 34 32 21 12 11 3 2 1
