最近板上又流行故事推理XD
我也找了一些題目
(不過有些頗白痴XD)
還滿簡單的啦 (′.ω.`)
------------------------------------
英國的科學家們發明了一個機器人,裡面有個簡單的程式(如下)
讓機器人通過一條車流量不致過高、非單行道的馬路
┌────────┐
│走到路旁停下 │
└────────┘
│
│
↓
┌────────┐
│往右看,往左看;│ ←─┐
│再往右看 │ │
└────────┘ │
│ │
↓ │
┌────────┐ 有 │
│附近30公尺內是否│ ──┘
│有交通工具? │
└────────┘
│無
↓
┌────────┐
│迅速通過馬路 │
└────────┘
(圖不精美請見諒m(ˍ ˍ)m)
然而,科學家們卻犯了一個錯誤,導致機器人花了將近九個小時才通過馬路
請問是什麼錯誤?
下方有答案!請確定思考之後再往下!
