Pemecah Kata Pencarian

Diberikan daftar kata dan kisi-kisi huruf, temukan semua kata dalam kisi dan hapus semua huruf yang bukan bagian dari kata-kata itu. Kata-kata itu bisa maju, mundur, naik, turun atau diagonal. Anda dapat berasumsi bahwa tidak ada kata dalam daftar yang akan muncul di lebih dari satu tempat di grid.

Input akan selalu: daftar kata, 1 per baris, diikuti oleh baris kosong, diikuti oleh kisi-kisi huruf.

Konsep di balik solusi ini adalah untuk mengulangi semua posisi di papan tulis, menginisialisasi nilai-nilai array 2D ke '' untuk setiap posisi, dan kemudian mempertimbangkan semua arah kata yang potensial dan offset kata. Jika kata yang cocok ditemukan, nilai array untuk posisi itu diperbarui ke huruf yang benar. Akhirnya, array dikonversi menjadi string dan dikembalikan.
