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. .
There are three square integers in the range: and . Return .
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
- int: the number of square integers in the range
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.

Test Case #00: In range , and are the two square integers.
Test Case #01: In range , there are no square integers.
