Square Numbers
A square number is an integer number whose square root is also an integer. For example 1, 4, 81 are
some square numbers. Given two numbers a and b you will have to ﬁnd out how many square numbers
are there between a and b (inclusive).
Input
The input ﬁle contains at most 201 lines of inputs. Each line contains two integers a and b (0 < a ≤
b ≤100000). Input is terminated by a line containing two zeroes. This line should not be processed.
Output
For each line of input produce one line of output. This line contains an integer which denotes how
many square numbers are there between a and b (inclusive).
Sample Input
1 4
1 10
0 0
Sample Output
2
3
