#Here is code to find all the patterns of "1(0 + ) 1" in a given string and the other steps required.

	last = str [ 0 ]
	i = 1 ; counter = 0
	while ( i < len ( str ) ) :
		if ( str [ i ] == '0' and last == '1' ) :
			while ( str [ i ] == '0' ) :
				i += 1
				if ( str [ i ] == '1' ) :
					counter += 1
		last = str [ i ]
		i += 1
	return counter
