Counting-Sort(A,B,k)

    let C[0..k] be a new array

    for i = 0 to k

           C[i] = 0

    for j = 1 to A.length

           C[A[j]] = C[A[j]] + 1

    //C[i] now contains the number of elements equal to i

    for i = 1 to k

           C[i] = C[i] + C[i-1]

     //C[i] now contains the number of elements less than or equal to i

     for j = A.length downto 1

           B[C[A[j]]] = A[j]

           C[A[j]] = C[A[j]] - 1
