Java的count计数java中count用法 Java的concurrent包里面的CountDownLatch其实可以把它看作一个计数器,只不过这个计数器的操作是原子操作,同时只能有一个线程去操作这个计数器,也就是同时只能有一个线程去减这个计数器里面的值。 你可以向CountDownLatch对象设置一个初始的数字作为计 ...
Here are the steps of our code this time: Initialize an integermaskto 0. Each bit inmaskwill represent a digit from 0-9. Iterate through each digit of the number. For each digit, create a bit representation. If the digit is d, then the bit representation is 1 << d. Use bitwise OR...
