# Find all the co binary numbers in the given range.

Find the number of co-binary palindromes existing between m and n. A co-binary palindrome is a number in which both, the decimal number and its binary conversion are a palindrome.

Examples:

```Input: starting number : 300, last number: 315

Output : 313
```

Code: Python code to find all the co binary numbers in the given range

 `# Python code for co-binary palindromes ` ` `  `def` `convert_into_binary(number): ` `    ``return` `bin``(number).replace(``"0b"``,"") ` ` `  `def` `reverse_it(number): ` `    ``number ``=` `str``(number) ` `    ``return` `number[::``-``1``] ` ` `  `def` `is_palindrome(number): ` `    ``if` `number ``=``=` `int``(reverse_it(number)) : ` `        ``return` `True` `    ``else``: ` `        ``return` `False` ` `  `# starting number ` `m ``=` `300` ` `  `# ending number ` `n ``=` `1000` `bin_pals ``=` `[] ` ` `  `for` `i ``in` `range``(m,n``+``1``): ` `    ``if` `is_palindrome(i) ``=``=` `True` `and` `is_palindrome( ` `            ``int``(convert_into_binary(i))): ` `         `  `        ``bin_pals.append(i) ` `         `  `print``(bin_pals) `

Output :

```[313, 585, 717]
```
