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

Dado um número inteiro n, impriman * reversed(n) reversed(n)é o número que você obtém quando reversedigita os 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 os pseudoprimes!

Introdução / Histórico Em uma discussão recente no chat de criptografia, fui desafiado a discutir / ajudar com o teste de primalidade de Fermat e os números de Carmichael. Esse teste é baseado na premissa que a^(p-1) mod p==1sempre será válida para primos p, mas nem sempre para compostos. Agora,...

Expand Cadeias de comparação

Diferentemente da maioria das linguagens, o Python avalia a<b<ccomo seria feito em matemática, na verdade comparando os três números, em vez de comparar o booleano a<bcom c. A maneira correta de escrever isso em C (e muitos outros) seria a<b && b<c. Nesse desafio, sua tarefa...

Contando matrizes circulantes ortogonais

Duas linhas de uma matriz são ortogonais se seu produto interno for igual a zero. Chame uma matriz com todas as linhas ortogonais pareadas e uma matriz ortogonal . Uma matriz circulante é aquela em que cada vetor de linha é girado um elemento para a direita em relação ao vetor de linha anterior....
