Please read question carefully.
First of all we have to take two 32 bit decimal numbers as input, and produce an unsigned 32 bit decimal number as the output.
– In above program we take x and y as input and answer as output.
– We have to take x and y value from user and convert them into 32 bit binary.
– And then we have to XOR them and convert to decimal number.  
– And after that we put it in answer variable and print it.

In java programming there is bitwise XOR operator which is ^ . We solved this problem very easily using this bitwise XOR operator.
