I was looking at the source of Java 1.6\'s Java.Util.ArrayDeque (a queue implementation) and stumbled on allocateElements() which should size the backing array according to the given number of element
#define XL33 #define OR113 #define NOR313 #define TN344 int to_bits(int critn,char *mask) { unsigned int x;
What is the most efficient algorithm to achieve the following: 0010开发者_如何学JAVA 0000 => 0000 0100
I have a table in which there is a bitwise column representing a list of statuses that can be attached to an entry. Each entry can have multiple statuses selected (hence the use of the bitwise logic).
I have an enmeration with a set of values which can be bitwise or\'d together: enum EventType_e { EventType_PING= 1,
two 32 bit numbers are given M and N . two bit positions are given i and j.The method should set all the bits between i and j in N equal to M .

I\'m trying to find out the best way to generate the following bitmask : - For a given input n, the output would be a bitmask which has the first (n-1) bits set, and all other bits unset开发者_如何转开
I want to find the value of a byte in a large integer. For example the number 11973777 = 10110110 10110100 10010001
I have a very typical situation. We have a table called Users which has a column called Branches (varchar 1000).
