Gagasan dari tantangan ini adalah untuk menemukan semua kata dari kamus di kotak surat. Masukan Anda harus berasal dari stdin atau fungsi arg dan akan datang dalam format berikut:

[your dictionary as a list of space sep words]
[a grid of letters]

Example:

The cool car
looc
thea
jopr

Aturan untuk menemukan kecocokan

Kecocokan valid jika ditemukan secara diagonal, horizontal, atau vertikal di papan tulis (tidak sensitif huruf). Arahnya tidak masalah (misalnya lookkecocokan kool). Jika ada beberapa kecocokan dari kata yang sama, tandai semuanya.

Keluaran:

Output Anda akan berupa grid yang Anda berikan - dengan perubahan kecil bahwa huruf-huruf akan dipisahkan dengan spasi dan garis-garis akan diberi spasi ganda. Contoh:

Input:
looc
thea
jopr

Output:
l o o c

t h e a

j o p r

Untuk mewakili kecocokan Anda akan menempatkan panah di antara huruf-huruf yang disatukan. Tanda panah ( /\-|X) akan menunjuk ke setiap pasangan huruf yang dikelompokkan dalam suatu pertandingan. Xdigunakan jika /\berpotongan.

Contoh:

Input:
The cool car
looc
thea
jopr

Output:
l-o-o-c
      |
t-h-e a
      |
j o p r

Input:

Input:

• Mengikuti komentar OP, abaikan casing dan paksa semua huruf kecil.
• Memperbaiki argumen, sekarang hanya argumen string tunggal yang terpecah

Catatan: menggunakan string template, ada 3 baris baru dalam kode yang signifikan dan dimasukkan dalam jumlah byte
