/*
	The media company "GlobalAd" has received a batch of advertisements from different product brands. 
	The batch of advertisements is a numeric value where each digit represents the
	number of advertisements the media company has received from different product brands.
	Since the company banners permit only even numbers of advertisements to be displayed, the
 	media company needs to know the total number of advertisements it will be able to
 	display from the given batch. Write an algorithm to calculate the total
	number of advertisements that will be displayed from the batch.


	Input The input consists of an integer batch, representing the batch of advertisements
	Output Print an integer representing the total number  of advertisements that will be displayed by the
	media company
	Constraints		0 < batchs 109?
