CF1629B.GCD Arrays
GCD Arrays
Consider the array composed of all the integers in the range . For example, if and , then .
Given , , and , is it possible for to be greater than after doing the following operation at most times?
- Choose numbers from .
- Permanently remove one occurrence of each of them from the array.
- Insert their product back into .
denotes the greatest common divisor (GCD) of the integers in .
Input
The first line of the input contains a single integer () — the number of test cases. The description of test cases follows.
The input for each test case consists of a single line containing non-negative integers , , and ($1 \leq l \leq r \leq 10^9, \enspace 0 \leq k \leq r - l$).
Output
For each test case, print "YES" if it is possible to have the GCD of the corresponding array greater than by performing at most operations, and "NO" otherwise (case insensitive).
Note
For the first test case, , so the answer is "NO", since the only element in the array is .
For the second test case the array is and we have operation. After the first operation the array can change to: , or all of which having their greatest common divisor equal to so the answer is "NO".
For the third test case, , so the answer is "YES", since the only element in the array is .
For the fourth test case, , so the answer is "YES", since the only element in the array is .
