In for loop it works like for example [1, 2, 3] first the value of i will taken as 1, 2 and 3 but you too told that it will work on 1^2, 2^3 but how it find the unique numbers when we give list like this [11, 22, 33, 11, 33] how it finds 22 if it works like this 11^22, 22^33, 11^33 how it will check like this 11^11, 33^33.can you please clear

Why, this approach is failing for the example - [1, 0, 2, 0, 4, 5, 3, 5, 4, 3]. Here it is giving 3 as answer, but 3 is repeating in this list
