EMTY2 - Can You Make It Empty 2 |
You are given a string S with only 0 and 1. You can delete the string 100 from any position of S an infinite number of times and obtain a new S after concatenation. Is it possible to make the string empty?
As for example, if S=101000 then 101000 → 100 → empty
If S=1010001 then 1010001 → 1001 → 1 → not empty
Input
Input starts with an integer T (≤ 100), denoting the number of test cases.
Each case contains a string S. The size of string is at most 120000.
Output
For each test case, print the case number and “yes” if it is possible to make the string S empty, print “no” otherwise.
Example
Input: 2 101000 1010001 Output: Case 1: yes Case 2: no
