Chef’s current rating is *X*, and he wants to improve it. It is generally recommended that a person with rating *X* should solve problems whose difficulty lies in the range [*X*,*X*+200], i.e, problems whose difficulty is at least *X* and at most *X*+200.

You find out that Chef is currently solving problems with a difficulty of *Y*.

Is Chef following the recommended practice or not?

- The first line of input will contain a single integer
*T*, denoting the number of test cases. The description of the test cases follows. - Each test case consists of a single line of input, containing two space-separated integers
*X*,*Y*.

For each test case, output on a new line `YES`

if Chef is following the recommended practice style, and `NO`

otherwise.

Each letter of the output may be printed in either lowercase or uppercase. For example, the strings `YES`

, `yEs`

, and `Yes`

will be considered identical.

- 1≤
*T*≤100 - 1≤
*X*,*Y*≤4000

Input: 5
1300 1500
1201 1402
300 4000
723 805
1330 512
Output: YES
NO
NO
YES
NO
```

**Test case 1:** Chef’s current rating is 1300, so he should solve problems with difficulty lying in [1300,1500]. Since 1500 lies in [1300,1500], Chef is doing his practice in a recommended way 🙂

**Test case 2:** Chef’s current rating is 1201, so he should solve problems with difficulty lying in [1201,1401]. Since 1402 does not lie in [1201,1401], Chef is not doing his practice in a recommended way 🙁

**Test case 3:** Chef’s current rating is 300, so he should solve problems with difficulty lying in [300,500]. Since 4000 does not lie in [300,500], Chef is not doing his practice in a recommended way 🙁

**Test case 4:** Chef’s current rating is 723, so he should solve problems with difficulty lying in [723,923]. Since 805 lies in [723,923], Chef is doing his practice in a recommended way 🙂

**Test case 5:** Chef’s current rating is 1330, so he should solve problems with difficulty lying in [1330,1530]. Since 512 does not lie in [1330,1530], Chef is not doing his practice in a recommended way 🙁

}
