Dada una entrada int n, imprima n * invertido (n)

Dado un número entero n, imprimirn * reversed(n) reversed(n)es el número que obtienes cuando tienes reverselos dígitos n. reverse(512) = 215 reverse(1) = 1 reverse(101) = 101 >>>>>>>> func(5) = 5*5 = 25 func(12) = 12*21 = 252 func(11) = 11*11 = 121 func(659) =...

Golf los pseudoprimes!

Introducción / antecedentes En una discusión reciente en el chat de cifrado, tuve el desafío de discutir / ayudar con la prueba de primalidad de Fermat y los números de Carmichael. Esta prueba se basa en la premisa que a^(p-1) mod p==1siempre se mantendrá para los primos p, pero no siempre para...

Expandir cadenas de comparación

A diferencia de la mayoría de los lenguajes, Python evalúa a<b<ccomo se haría en matemáticas, comparando en realidad los tres números, en lugar de comparar el booleano a<bcon c. La forma correcta de escribir esto en C (y muchas otras) sería a<b && b<c. En este desafío, su...

Contando matrices circulantes ortogonales

Dos filas de una matriz son ortogonales si su producto interno es igual a cero. Llame a una matriz con todas las filas ortogonales por pares una matriz ortogonal . Una matriz circulante es aquella en la que cada vector de fila gira un elemento a la derecha en relación con el vector de fila...
