Can you provide a code to longest subsequence with a given AND value and the other steps required given the following:
Longest subsequence with a given AND value | O ( N ) | Function to return the required length.
To store the filtered numbers.
Filtering the numbers.
If there are no elements to check.
Find the OR of all the filtered elements.
Check if the OR is equal to m.
Driver code"
How can the above be solved in Python?

	for i in range ( n ) :

	if ( len ( filter ) == 0 ) :
		return 0 ;
	c_and = filter [ 0 ] ;
	for i in range ( 1 , len ( filter ) ) :
