Initialize an array. Size should be more than FIVE. Write you program to change the array in such a way so that there cannot be any duplicate element in the array anymore. Print the changed array. If the initialized array already had no duplicate elements from the beginning, output a message saying $$Array already unique!$$;

For example,

Scenario $1$:

Array$\_1=\{1,4,6,3,6,9,1\}$

Output: $14639$

Scenario $2$:

Array$\_1=\{1,4,5,3,6,9\}$

Output: Array already unique!

Write and explain in Cpp$.$
