yaeh...
100 - is valid in 10-digit system
55400342 - is valid in 5-digit system...

> So, two successful zeros is zero, and after it another
one zero, example: 1001123.
There can't be leader zeros, such as 0123; 0123 - is 3-
digits number.

Re:100,55400342 are valid?The problem says that valid number is a number doesn't contain two successful zeros,but 100 contain two zeros which are continuous.

Does the word "successful" means "consecutive"
or "continuous"?Does it mean that the valid number mustn't
contain two and more than two consecutive zeros (certainly
not in the head)?
For example,101010 is valid,but 101100 and 111000 is not
valid,right?

You are certainly right. Pay attention on the task's condition!
