A: thief != 'D' && thief != 'B' && thief != 'C'
B: thief != 'A' && thief != 'B' && thief != 'D'
C: thief == 'C'
D: thief != 'D' && thief != 'B'
举一反三
- 下面逻辑表达式，与表达A表达的意思相同的有： A: thief != 'D' && thief != 'B' && thief != 'C' B: thief != 'A' && thief != 'B' && thief != 'D' C: thief == 'C' D: thief != 'D' && thief != 'B'
- 4个盗窃(thief) A,B,C,D中有一个盗贼下面逻辑表达式，与表达“C说：D哥是我的好兄弟，我俩肯定没干这事儿。”表达的意思相同的有： A: thief != 'D' B: thief != 'D' || thief != 'C' C: thief != 'D' && thief != 'C' D: thief == 'A' || thief == 'B'
- 4个盗窃(thief) A,B,C,D中有一个盗贼下面逻辑表达式，与表达“是A干的。如果不是A，就是B。如果还不是，就是C。”表达的意思相同的有： A: thief == 'A' B: thief == 'B' C: thief == 'C' D: thief == 'A' || thief == 'B' || thief == 'C'
