Minimum size of the array with MEX as A and XOR of the array elements as B | Function to find the minimum size of array with given MEX and XOR.
Find the XOR of values from 0 to A - 1.
If A is a multiple of 4.
If A % 4 gives remainder 1.
If A % 4 gives remainder 2.
Initializing array size by A.
If XOR of all values of array is equal to B.
If the required integer to be added is equal to A.
Else any integer can be added.
