Tingkat coding: Pemula Durasi: 5 menit Jenis project: Otomatisasi dengan menu kustom

Tujuan

  • Pahami fungsi solusi.
  • Pahami fungsi layanan Apps Script dalam solusi.
  • Siapkan skrip.
  • Jalankan skrip.

Tentang solusi ini

Buat bagan turnamen untuk hingga 64 orang atau tim. Solusi ini membuat diagram pohon yang merepresentasikan turnamen sistem gugur.

Contoh bagan turnamen yang telah selesai

Cara kerjanya

Skrip mengulang daftar pemain dan menentukan berapa banyak babak yang diperlukan dalam bagan. Skrip memformat sheet Bracket untuk membuat diagram pohon dan menambahkan nama pemain ke babak pertama.

Layanan Apps Script

Solusi ini menggunakan layanan berikut:
