生成的密碼和用戶輸入可以接受重復數字。
所以相對一般規則的猜數字可能難度要大不少。
本版本規則：
A--數字對，位置也對
B--排除A的結果后，數字對，但位置不對
開始后，系統化初始化一個4位可重復數字，如“1223”。假設用戶第一次輸入“1234”，那么系統將提示“2A1B”，前兩位數字“12”相同并且位置也相同，為“2A”。后兩位數字中，用戶輸入的“3”與密文中“3”相同，但兩者位置不同，則為“1B”，最終結果為“2A1B”。
再假設用戶此時輸入“1232”，那么結果則為“2A2B”，計算方法與前次一樣。
代碼如下：
#!/bin/bash
clear

echo "###################################################################"
echo "# this is a bash-shell game write by Email:breeze7086@gmail.com #"
echo "# the game called *digits*,and this version have repeated numbers #"
echo "# version 1.0 #"
echo "###################################################################"
echo -e "\n\n"
