Answer:
It goes like:
public class Program
{
public static void main(String[] args)
{
int j=18;
int sum=0;
for (int i =1; i<7; i++)
{
sum=sum+(i*(j-2));
j=j-2;
}
System.out.println(sum);
}
}
Explanation:
<u>Variables used: </u>
j : controls the first number in product and decreases by 2 each time the loop runs.
sum: saves the values of addition as the loop runs.
When a formula produces output that is too lengthy to fit in the spreadsheet cell, the error that will show is "#####". When you enter an invalid cell reference in a formula, for instance using "AVE(" instead of "AVERAGE("; the error that will show is "#NAME?". When you type text in cells that accept numeric data, for instance adding 1 + 1 + A; then the error that will show is "#VALUE". Lastly, when you type in a cell reference that does not exist, the error that will show is "#REF".
This is a tough question. I’m not sure if I’ll get it right but I’ll try.
Data structures used for file directories typically have a hierarchical tree structure, referred to as a directory structure. The tree has a root directory, and every file in that system has a unique path.
The simplest method of implementing a directory is to use a linear list of file names with pointers to the data blocks. But another way that you can format a file directory is by using a hash table. With this method, the linear list stores the directory entries, but a hash data structure is also used. The hash table takes a value computed from the file name and return the pointer to the file name any linear list.
So I think it’s C. But I’m not 100% sure.
I hope that helps.
