Diberikan input int n, cetak n * terbalik (n)

Diberikan bilangan bulat n, cetakn * reversed(n) reversed(n)adalah angka yang Anda dapatkan ketika Anda reversedigit 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) =...

Luaskan Chains Perbandingan

Tidak seperti kebanyakan bahasa, Python mengevaluasi a<b<ckarena akan dilakukan dalam matematika, sebenarnya membandingkan tiga angka, yang bertentangan dengan membandingkan boolean a<buntuk c. Cara yang benar untuk menulis ini dalam C (dan banyak lainnya) adalah a<b &&...
