Given two integer arrays arr1 and arr2, return the minimum number of operations (possibly zero) needed to make arr1 strictly increasing. In one operation, you can choose two indices 0 <= i < arr1.length and 0 <= j < arr2.length and do the assignment arr1[i] = arr2[j]. If th...
实时上java会分两步写入这个long变量,先写32位,再写后32位。这样就线程不安全了。如果改成下面的就线程安全了: 1 privatevolatilelongfoo; 因为volatile内部已经做了synchronized. CAS无锁算法 要实现无锁(lock-free)的非阻塞算法有多种实现方法,其中CAS(比较与交换,Compare and swap)是一种有名的无锁算法。CAS...
In themain()function, we created and initialized an arrayarrand also created atempvariable. // Swap adjacent elements for i:=0;i<=4;{ temp = arr[i] arr[i] = arr[i + 1] arr[i + 1] = temp i=i+2 } In the above code, we swapped adjacent elements in the array. After that...
