CRC calculation
Or in hex and binary:
0x 01 04 C1 1D B7
1 0000 0100 1100 0001 0001 1101 1011 0111
The highest term (x32) is usually not explicitly written, so it can instead be represented in hex just as
0x 04 C1 1D B7
Feel free to count the 1s and 0s, but you'll find they match u...
How does a hash table work?
... above, each of the 300 filing cabinet would (statistically) contain about 100 records. Searching (regardless the order) through 100 records is much faster than having to deal with 30,000.
You may have noticed that some actually already do this. But instead of devising a hashing methodology to ge...

Generating a Random Number between 1 and 10 Java [duplicate]
... try something like this.
Random rn = new Random();
for(int i =0; i < 100; i++)
{
int answer = rn.nextInt(10) + 1;
System.out.println(answer);
}
Also if you change the number in parenthesis it will create a random number from 0 to that number -1 (unless you add one of course like you ...

What is the behavior of integer division?
... positive values they are the same
int integerDivisionResultPositive= 125/100;//= 1
double flooringResultPositive= floor(125.0/100.0);//=1.0
For negative value this is different
int integerDivisionResultNegative= -125/100;//=-1
double flooringResultNegative= floor(-125.0/100.0);//=-2.0
