Surprisingly there are only three numbers that can be written as the sum of fourth powers of their digits: 1634 = 14 + 64 + 34 + 44 8208 = 84 + 24 + 04 + 84 9474 = 94 + 44 + 74 + 44 As 1 = 14 is not a sum it is not included. The sum of these numbers is 1634 + 8208 + 9474 = 19316. Find the sum ...

The number, 197, is called a circular prime because all rotations of the digits: 197, 971, and 719, are themselves prime. There are thirteen such primes below 100: 2, 3, 5, 7, 11, 13, 17, 31, 37, 71, 73, 79, and 97. How many circular primes are there below one million? Here's my implementation ...

As you probably know, python slices like arr[1:3] etc. do NOT provide a view onto list and instead creates a copy of the list, what can be not optimal performance if array is big and you make for example arr[1:] (copies all exept first) the idea ov a view to an array is like : class ylist_view(...
