【题目】如图3是计算机中的一种益智小游戏“扫雷”的画面,在一个9×9的小方格的正方形雷区中,随机埋藏着10颗地雷,每个小方格内最多只能藏1颗地雷.李强在游戏开始时首先随机地踩中一个方格,猜中后出现了如图3所示的情况,我们把与标号3相邻的方格记为 A 区域(画线部分),数字3表示 A 区域有3颗地雷.然后李强又踩中左上角第一个方格,猜中后出现了如图3所示的情况,我们把与标号1相邻的方格记为B区域(画线部分),数字1表示 A区域有1颗地雷,A 区域与 B 区域外的部分记为 C 区域.
[Topic] As shown in Figure 3 is a computer puzzle game “mine clearance” screen, in a 9 × 9 small squares square mined area, randomly buried 10 mines, each small square Grid can only hide a maximum of one mine.Li Qiang at the beginning of the game first randomly in a square, guess after appeared as shown in Figure 3, we put the box adjacent to label 3 marked A Area (line drawing part), the number 3 indicates that there are 3 mines in area A. Then Li Qiang stepped on the first square in the upper left corner again, as shown in Figure 3 after guessing, we put adjacent to label 1 The square is marked as area B (line drawing), the number 1 indicates that there is 1 landmine in area A, and the area outside area A and area B is marked as area C.
