text: Find a number such that maximum in array is minimum possible after XOR | Recursive function that find the minimum value after exclusive - OR ; Condition if ref size is zero or bit is negative then return 0 ; Condition if current bit is off then push current value in curr_off vector ; Condition if current bit is on then push current value in curr_on vector ; Condition if curr_off is empty then call recursive function on curr_on vector ; Condition if curr_on is empty then call recursive function on curr_off vector ; Return the minimum of curr_off and curr_on and add power of 2 of current bit ; Function that print the minimum value after exclusive - OR ; Pushing values in vector ; Printing answer ; Driver Code
