macro bit set

Each element in the Set occupies only one binary bit. A set of less than eight elements only needs one byte. First observe the size of the Set: Type tset1 = set of (A1, A2, A3, A4, A5, A6, A7, A8); {exactly corresponds to eight bytes} tset2 =

stream looks for 0 and 1, for example, if you enter the following:10121Input stream will be read into 101,21 will be left.For bytes and words, the bits in the bitset are numbered from right to left (from the least significant bit to the most significant bit). Thus, the value of the 7th bit is 27; 7: 6: 5: 4: 3: 2: 1:

The first two days to replace the CD-ROM drive, tossing a long time to fix the dual system, here Memo:The optical drive is broken, and there is a hard drive that was previously removed from the notebook and is going to be mounted on the drive:My notebook is Sony, that need to install to the CD-ROM drive is removed from this notebook, there is a genuine Win7 system, but a long time no use.Since the optical drive is broken, buy an optical disk drive tray, put that hard drive back to use Bai.After

Because Java has a convenient String integer.tobinarystring (int), when learning to generate a subset of the algorithm to generate a power set with a bit string, think of Java implementation. Power set is very useful when solving knapsack problem, brute force method, simple and rough effective, of course, limited to small examples.Implement the following Powerset

Principle Introduction:The Java platform's BitSet is used to hold a bit sequence, and if you want to store a bit sequence efficiently, you can use a bit set (BitSet). Because bit sets wrap bits in bytes, using a bit

Title: Give a 1 to n full arrangement, M query, delete one number at a time, output the total reverse logarithm.Idea: Each node in the tree array is treap, with a bit set of treap to find out how many smaller numbers are in front of each point ...The idea is still relatively simple, but wrote for a long time, now a very serious drawback is that the code of a large amount of no fixed force, and then directly

Only one number appears once in a set of data. All other numbers appear in pairs. Please find out the number. (using bit operations)Solution: Program:#include int Main (){int arr[] = {1,3,3,1,4,9,4,5,5};int i = 0;int len = sizeof (arr)/ sizeof (Arr[0]); for (i = 1; i {Arr[0] = arr[0] ^ arr[i]; //Put all the numbers in this set of digits to the bitwise OR, becaus
