  1. Kuliah Ke-4 Antrian / Queue (Bab 4) Informatics Engineering DeptTRUNOJOYO UNIVERSITY

  2. Kita lanjutkan untuk yang satu ini …..

  3. ANTRIAN / QUEUE Struktur Data • Definisi: • struktur data (mirip stack) yang memperbolehkan penyisipan di belakang (rear) dan penghapusan elemen di depan (front) • Contoh : • Penjualan karcis kereta, bioskop • Penjadualan pencetakan (spooling system) • Penjadualan pemakaian CPU • Pemakaian I/O pada sistem komputer • Penyimpan barang di Apotek

  4. MODEL ANTRIAN / QUEUE Struktur Data Kosong 1 Elemen 4 Elemen D Belakang Belakang Belakang 0 1 4 C B Depan Depan Depan A A 0 1 1

  5. OPERASI DASAR A n t r I a n • Dua operasi dasar ANTRIAN : • TAMBAH • AMBIL AMBIL TAMBAH

  6. TAMBAH ELEMEN Struktur Data Antrian Depan = 0 B A C D Belakang = 0 Depan = 1 Depan = 1 Belakang = 4 Belakang = 2 Depan = 1 Depan = 1 Belakang = 1 Belakang = 3

  7. AMBIL ELEMEN Struktur Data Antrian B A C D Ambil 1 elemen Geser antrian Depan = 1 Belakang = 3

  8. AMBIL ELEMEN Struktur Data Antrian C B D Ambil 1 elemen Geser antrian Depan = 1 Belakang = 2

  9. AMBIL ELEMEN Struktur Data Antrian D C Ambil 1 elemen Geser antrian Depan = 1 Belakang = 1

  10. AMBIL ELEMEN Struktur Data Antrian D Ambil 1 elemen Depan = 0 Belakang = 0

  11. KAMUS DATA Antrian Kamus Data : Q : array [1..4] of Char Depan : Integer Belakang : Integer Q Belakang 0 Depan 0

  12. Kondisi Antrian Struktur Data Kosong 1 Elemen Penuh D Belakang Belakang Belakang 0 1 4 C B Depan Depan Depan A A 0 1 1

  13. ANTRIAN SIRKULER A n t r I a n Model ini sama dengan antrian biasa, hanya saja : TIDAK ADA PERGESERAN AMBIL TAMBAH

  14. TAMBAH ELEMEN Antrian Sirkuler Depan = 0 B A C D Belakang = 0 Depan = 1 Depan = 1 Belakang = 4 Belakang = 2 Depan = 1 Depan = 1 Belakang = 1 Belakang = 3

  15. AMBIL ELEMEN Antrian Sirkuler Ambil 1 elemen B A C D Depan = 2 Belakang = 4

  16. AMBIL ELEMEN Antrian Sirkuler Ambil 1 elemen B C D Depan = 3 Belakang = 4

  17. AMBIL ELEMEN Antrian Sirkuler Ambil 1 elemen C D Depan = 4 Belakang = 4

  18. TAMBAH ELEMEN Antrian Sirkuler Tambah 1 elemen E D Depan = 4 Belakang = 1

  19. TAMBAH ELEMEN Antrian Sirkuler Tambah 1 elemen F E D Depan = 4 Belakang = 2

  20. TAMBAH ELEMEN Antrian Sirkuler Tambah 1 elemen F E G D Depan = 4 Belakang = 3

  21. TAMBAH ELEMEN Antrian Sirkuler Tambah 1 elemen F E G D Antrian Overflow Depan = 4 Belakang = 3

  22. Kondisi Antrian Sirkuler Struktur Data Kosong 1 Elemen Penuh D Belakang Belakang Belakang 0 1 4 C B Depan Depan Depan A A 0 1 1
