Use this problem to bring awareness of bit manipulation in interviews, it's rare but sometimes do get asked by some interviewers. We can directly use Java's Integer.reverse() method, not suitable for interview purpose. Simple simulation, reading bits from the right most and adding them up wh...
Java only has signed types: >> will sign-extend values (which is probably not what you want), but the Java-specific operator >>> will shift in zeros. Cute tricks There are a few other tricks that can be done with bit manipulation. They’re good for amazing your ...
Note that in some languages such as Java, there is no unsigned integer type. In this case, the input will be given as signed integer type and should not affect your implementation, as the internal binary representation of the integer is the same whether it is signed or unsigned. In Java,...

我有一节课 def apply(myRDD: RDD[String]) { // do String manipulation }object MyClass { 因为我有一段代码来执行一个任务(表示"do String manipulation"的区域),所以我想我应该把它分解成它自己的方法。由于该方法不会更改类的状态,因此我认为应该将其设置为static方法。我认为你只需要在伴生对象...
