It was invented by Osborne<span> Computers</span>
The choices can be found elsewhere and as follows:
<span>a. caches
b. landing pages
c. Web crawlers
d. proxy servers
e. interstitials
</span>
I believe the correct answer is option C. Search engines use web crawlers to discover documents for indexing and retrieval. It is also known as spiders. It <span>is a software that traverses available Web links in an attempt to perform a given task.</span>
<span>Ben has to write a note on color concepts. Help him complete the following sentences.
When light hits a surface, the surface absorbs some of the light and reflects the rest. The color that you see depends on which light waves the surface reflects
( reflects, absorbs, emits) the most. You perceive objects as having a specific color because of these constituent ______( rays, colors, intensities) of light.
I wasn't sure on the last one.</span>
Answer:
class Main {
static void printPowers(int howMany, int nrRows) {
for(int n=1; n<=nrRows; n++) {
for(int power = 1; power<=howMany; power++) {
System.out.printf("%d ", (int) Math.pow(n, power));
}
System.out.println();
}
}
public static void main(String[] args) {
printPowers(3, 5);
}
}
class Main {
static void printPowers(int howMany, int nrRows) {
int n = 1;
do {
int power = 1;
do {
System.out.printf("%d ", (int) Math.pow(n, power));
power++;
} while (power <= howMany);
System.out.println();
n++;
} while (n <= nrRows);
}
public static void main(String[] args) {
printPowers(3, 5);
}
}
Explanation:
The for loop gives the cleanest, shortest code.
