blow判定注意
バグ発見．
blow = 0
for j in range(4):
for i in range(4):
if (int(b[j])==a[i]) and (int(b[i])!=a[i]) and(int(b[j])!=a[j]):
blow = blow + 1
break
だと，randomで作った数字が
[0,1,6,0]
に対して
[6,6,1,0]
と予測した場合に，
hit:1 blow:3
と判断される．正しくは，
hit:1 blow:2
でないとだめ．
- 重複した数字を選ばないようにするか，
- はたまた，より厳密にblowを判断させるか．．．
より厳密なblow判定をさせるのは以下の通り．意外とめんどい．もっと楽なやり方があれば教えてください．
