Ninja has created his own encryption technique to encrypt a number. He makes use of the logic behind factorial. In a factorial, we multiply the number by its previous number and so on but if we want to encrypt a number we don’t multiply in every step like in the case of factorial but multiply, divide, add and subtract and repeat in the same order.

So your task is to find the encrypted form of a number using the ninja encryption technique and you were being provided with the number.

You are given an array of integers ‘A’ having ‘N’ number of elements. It is given that all the numbers in the array occur twice except the two numbers that appear only one time. You need to find those two non-repeating numbers.

For Example:

If the given array is [ 4, 7, 3, 2, 7, 2 ], you have to find ‘4’ and ‘3’ as 4 and 3 occur one time, and the rest of the elements ( 7 and 2 ) are occurring twice.

The basic divide a cake in4 equal parts but only with 2 cuts
