#Here is code to find lost element from a duplicated array and the other steps required.
 def findMissing ( arr1 , arr2 , M , N ) :
	if ( M != N - 1 and N != M - 1 ) :
		print ( " Invalid ▁ Input " )
		return
	res = 0
	for i in range ( 0 , M ) :
		res = res ^ arr1 [ i ] ;
	for i in range ( 0 , N ) :
		res = res ^ arr2 [ i ]
	print ( " Missing ▁ element ▁ is " , res )
arr1 = [ 4 , 1 , 5 , 9 , 7 ]
arr2 = [ 7 , 5 , 9 , 4 ]
M = len ( arr1 )
N = len ( arr2 )
findMissing ( arr1 , arr2 , M , N )
