For you, numbers have personalities. The number 4 is elegant, 18 is strong and 42 is enigmatic. And, of course, any number ending in 0 is cute.
The more zeroes at the end of a number, the cuter that number is. Therefore 70, 36640 and 1800090 are only a little bit cute (ending in just one zero), whereas 400 and 99200 are very cute (ending in two zeroes) and 30000 is really really cute (ending in four zeroes).
Your task is to read in a number N and determine how many zeroes are at the end of that number, so you can tell just how cute the number is.
