※ 引述《linjack (嗯)》之銘言：
: --- 九九乘法
: 1.upto(9) { |i|
: 1.upto(9) { |j|
: printf "%d*%d=%2d ", i, j, i*j
: }
: print "\n"
: }
: ---
90.times{ |i|
printf "%d*%d=%2d ", i/10+1, i%9+1, (i/10+1)*(i%9+1)
puts if (i+1)%9 == 0
}
好像很爛 = =b
只是把雙迴圈拆成單迴圈而已

I am a wizard without a home. I am a wonderer seeking refuge.
