Give me a code to check if a symmetric plus is possible from the elements of the given array and the other steps required given the following:
Check if a symmetric plus is possible from the elements of the given array | Function that return true if a symmetric is possible with the elements of the array.
Map to store the frequency of the array elements.
Traverse through array elements and count frequencies.
For every unique element.
Element has already been found.
The frequency of the element something other than 0 and 1.
Driver code"

#Here is code to check if a symmetric plus is possible from the elements of the given array and the other steps required.
 def isPlusPossible ( arr , n ) :
	mp = dict ( )
	for i in range ( n ) :
		mp [ arr [ i ] ] = mp . get ( arr [ i ] , 0 ) + 1
	foundModOne = False
	for x in mp :
		element = x
		frequency = mp [ x ]
		if ( frequency % 4 == 0 ) :
			continue
		if ( frequency % 4 == 1 ) :
			if ( foundModOne == True ) :
				return False
			foundModOne = True
		else :
			return False
	return True
arr = [ 1 , 1 , 1 , 1 , 2 , 2 , 2 , 3 , 2 ]
n = len ( arr )
if ( isPlusPossible ( arr , n ) ) :
	print ( " Yes " )
else :
	print ( " No " )
