How do shift operators work in Java? [duplicate]
...ng(2 << 11));
Shifts binary 2(10) by 11 times to the left. Hence: 1000000000000
System.out.println(Integer.toBinaryString(2 << 22));
Shifts binary 2(10) by 22 times to the left. Hence : 100000000000000000000000
System.out.println(Integer.toBinaryString(2 << 33));

...这也是最笨的一种方式,当然最终能够猜对,当随机数是100时,最多需要猜100次。
再设计一个二分算法,每次猜中间折半的结果,比如第一次猜50,如果小了则再猜75,如此直到不能再折半为止,也定能猜中。至于需要几次猜...
