Answer:
C. sqrt(Math)
Explanation:
All but one of options A to E are is not a static method.
Only option C is a static method. The sqrt() is a static method of Math, that can always be used as Math.sqrt() is used;
The Math class defines all of its methods to be static. Invoking Math methods is done by using Math as a method rather than a variable of type Math; this means that sqrt(Math) doesn't rely on instance variables and don't need to be overridden, unlike others.
Lastly, sqrt(Math) is a static method because unlike other options, it is an utility method, and it is relevant to computations on primitive data types.
The purpose of the static method is in large part to offer a standard library of functions, and it doesn't need to be applied directly to an object.
Answer:
to set up placeholders in a document where data will be inserted
Answer:
Running time of algorithm is O(n).
Explanation:
n is power of 2
n =2,4,8,16,32,...................................
A is an array having n elements
B is an array of size 0 to (n/2)-1
if n=4 B then (4/2)-1 =1 So B has size 2
for(i=0;i<=(n/2)-1;++)
{
B[i]=A[2i]+A[2i+1];
}
This for loop will run n/2 times so complexity in terms of Big Oh is O(n/2) =O(n)
Running time of algorithm is O(n).
Answer:
3 * 5 + 4 ** 2 - 1 = 5
