# Sum Numbers But 5

Here's a basic challenge to get started.
In each test case, you will be given two numbers `a`

and `b`

. The *fiveless sum* of a range of numbers is the sum of all the numbers from `a`

to `b`

(inclusive) except for any multiple of 5. Print out the *fiveless sum* of each given pair of numbers.

For example, if you're given 1 and 6 as input, print out 16.

(1+2+3+4+6 = 16)

**Range**

-10,000,000 < a < b < 10,000,000

**Input Format**

You are provided with boilerplate code to process the input, but here's the format in case you want to do it yourself:

The first line contains `t`

for the number of test cases. `t`

lines follow which each contain one two integers `a`

and `b`

.

**Output Format**

Output the *fiveless sum* for each pair of integers on its own line.

**Sample Input**

2 1 6 -7 17

**Sample Output**

16 100

*Note: To pass the contest part in Ruby, you'll need to optimize your code a bit...*
