+PENJELASAN

+Program ini dibuat untuk mencari satu angka yang hilang dari deretan angka yang sebenarnya berurutan. Angka-angka tersebut digabung jadi satu string tanpa spasi, jadi program akan membongkar dan mengecek urutannya satu per satu sampai ketemu angka yang tidak ada, lalu langsung menampilkan angka yang hilang secara otomatis menggunakan Python.
