# Sherlock and Squares

Watson likes to challenge Sherlock's math ability. He will provide a starting and ending value that describe a range of integers, inclusive of the endpoints. Sherlock must determine the number of *square integers* within that range.

**Note**: A square integer is an integer which is the square of an integer, e.g. .

**Example**

There are three square integers in the range: and . Return .

**Function Description**

Complete the *squares* function in the editor below. It should return an integer representing the number of square integers in the inclusive range from to .

squares has the following parameter(s):

*int a:*the lower range boundary*int b:*the upper range boundary

**Returns**

*int:*the number of square integers in the range

**Input Format**

The first line contains , the number of test cases.

Each of the next lines contains two space-separated integers, and , the starting and ending integers in the ranges.

**Constraints**

**Sample Input**

```
2
3 9
17 24
```

**Sample Output**

```
2
0
```

**Explanation**

*Test Case #00:* In range , and are the two square integers.

*Test Case #01:* In range , there are no square integers.
