MNUMBER - Mono Numbers |
Given a number, find if it is possible to convert it into a mono-number. If all the digits of a number are same, it is a mono-number.
Examples: 666, 7, 11, 55555555555555555555.
Only one operation is allowed: You can replace two adjacent digits of the number by their sum. Digit(s) that are a result of sum of two digits cannot be involed in any further operations. There is no limit on the number of operations.
Example:
123 => (1+2)3 => 33
675 => 6(7+5) => 613
(Though this is a valid operation, it is useless as we can never get a mono-number this way as the resultant itself has two different digits)
Input
First line contains T, the number of test cases.
Next T lines contain N, the number that should be converted to a mono-number.
Output
For each test case a line:
If it is possible, output "YES", else output "NO".
Constraints
T can be as high as 1000.
N can have upto 20 digits.
Example
Input: 4 123 23232323232323 7734716752 12345678 Output: YES YES YES NO
Explanation
First test case is explained in the problem statement.
In second, all the digits can be made 5, by adding adjacent 2 and 3s.
In third, all digits can be converted to 7.
