Answer: (C) Sorting and charting data from surveys.

Explanation:

A computerized spreadsheet is basically used for sorting and charting the data from the survey. Sp[reed sheet is one of the computer application that are used for the storing and also analysis the data in the tabular form.

Spreadsheet is mainly develop in the form of computerized analogs which is used as the paper accounting worksheet. In the spreadsheet we can also perform various types of mathematical calculations and the arithmetic functions.

Therefore, Option (C) is correct.

Which access control principle specifies that no unnecessary access to data exists by regulating members so they can perform onl

sdas [7]

Least privilege is the data access principle that ensures to unnecessary access to data exists by regulation members so that can perform only minimum data manipulation necessary. The principle of least privilege or as called as POLP is the run-through of controlling access to the minimal level that will permit normal functioning. The norm of least privilege interprets to giving people the lowermost level of user right that they can have and still do their jobs. The principle is also functional to things other than people as well as programs and processes. It is created in the US department of defense in the 1970’s and aimed to limit the potential damage of any security breach either accidental or malicious.

Recall the problem of finding the number of inversions. As in the text, we are given a sequence of n numbers a1, . . . , an, whi

Kay [80]

Answer:

The algorithm is very similar to the algorithm of counting inversions. The only change is that here we separate the counting of significant inversions from the merge-sort process.

Algorithm:

Let A = (a1, a2, . . . , an).

Function CountSigInv(A[1...n])

if n = 1 return 0; //base case

Let L := A[1...floor(n/2)]; // Get the first half of A

Let R := A[floor(n/2)+1...n]; // Get the second half of A

//Recurse on L. Return B, the sorted L,

//and x, the number of significant inversions in $L$

Let B, x := CountSigInv(L);

Let C, y := CountSigInv(R); //Do the counting of significant split inversions

Let i := 1;

Let j := 1;

Let z := 0;

// to count the number of significant split inversions while(i <= length(B) and j <= length(C)) if(B[i] > 2*C[j]) z += length(B)-i+1; j += 1; else i += 1;

//the normal merge-sort process i := 1; j := 1;

//the sorted A to be output Let D[1...n] be an array of length n, and every entry is initialized with 0; for k = 1 to n if B[i] < C[j] D[k] = B[i]; i += 1; else D[k] = C[j]; j += 1; return D, (x + y + z);

Runtime Analysis: At each level, both the counting of significant split inversions and the normal merge-sort process take O(n) time, because we take a linear scan in both cases. Also, at each level, we break the problem into two subproblems and the size of each subproblem is n/2. Hence, the recurrence relation is T(n) = 2T(n/2) + O(n). So in total, the time complexity is O(n log n).

Which of the following statements represents the number of columns in a regular two-dimensional array named values?

puteri [66]

Answer:

(a) values[0].length

Explanation:

In programming languages such as Java, an array is a collection of data of the same type. For example, a and b below are an example of an array.

a = {5, 6, 7, 9}

b = {{2,3,4}, {3,5,4}, {6,8,5}, {1,4,6}}

But while a is a one-dimensional array, b is a regular two-dimensional array. A two-dimensional array is typically an array of one-dimensional arrays.

Now, a few thing to note about a two-dimensional array:

(i) The number of rows in a 2-dimensional array is given by;

arrayname.length

For example, to get the number of rows in array b above, we simply write;

b.length which will give 4

(ii) The number of columns in a 2-dimensional array is given by;

arrayname[0].length

This is with an assumption that all rows have same number of columns.

To get the number of columns in array b above, we simply write;

b[0].length which will give 3

Therefore, for a regular two-dimensional array named values, the number of columns is represented by: values[0].length
