Given a range

`[l; r]`

, you would like to know how many special numbers are there in that range. A number `n`

is special if its power of 3 is divisible by 5 or by 7 (

is divisible by 5 or 7).The input contains 2 numbers

`l`

and `r`

(1 ≤ l ≤ r ≤ 1000).Print how many special numbers are there in the

`[l; r]`

range (the range is inclusive).Input | Output |
