We shall say that an n-digit number is pandigital if it makes use of all the digits 1 to n exactly once.

For example, 2143 is a 4-digit pandigital and is also prime.

What is the largest n-digit pandigital prime that exists? 765 2413

The decimal number, 585 = 1001001001 base2 (binary), is palindromic in both bases.

Find the sum of all numbers, less than one million, which are palindromic in base 10 and base 2.

(Please note that the palindromic number, in either base, may not include leading zeros.)

Count Files Matching A Certain Pattern

Option 1 - recursive

ls -1f | grep wav | wc -l

Option 2 - only current dir

find . -maxdepth 1 -name "*wav" | wc -l
