Write me a code to lexicographic rank of a Binary String and the other steps required given the following:
Lexicographic rank of a Binary String | Function to find the rank of a string.
Store the length of the string.
Stores its equivalent decimal value.
Traverse the string.
Store the number of strings of length less than N occurring before the given string.
Store the decimal equivalent number of string bin.
Store the rank in answer.
Prthe answer.

#Here is code to lexicographic rank of a Binary String and the other steps required.
 def findRank ( s ) :
	N = len ( s ) ;
	sb = " " ;
	for i in range ( 0 , N ) :
		if ( s [ i ] == '0' ) :
			sb += str ( '0' ) ;
		else :
			sb += str ( '1' ) ;
	bin = str ( sb ) ;
	X = pow ( 2 , N ) ;
	Y = int ( bin ) ;
	ans = X + Y - 1 ;
	print ( ans ) ;
if __name__ == ' _ _ main _ _ ' :
	S = "001" ;
	findRank ( S ) ;
