The complete program is to define a boolean method that returns true if all elements of an array are negative, or return false, if otherwise

The method in java, where comments are used to explain each line is as follows:

//This defines the method

public static boolean chkNegative (double[] myArr) {

//This initializes a boolean variable

boolean isNeg = true;

//This iterates through the array

for (int i = 0; i < myArr.length; i++) {

//If the array element is 0 or positive

if (myArr[i] >= 0) {

//Then the boolean variable is set to false

isNeg = false;

//And the loop is exited

break;

}

//This returns true or false

return isNeg;

}

Consider two vectors that are NOT sorted, each containing n comparable items. How long would it take to display all items (in an

Darina [25.2K]

Answer:

The correct answer to the following question will be "Θ(n2)

". The further explanation is given below.

Explanation:

If we're to show all the objects that exist from either the first as well as the second vector, though not all of them, so we'll have to cycle around the first vector, so we'll have to match all the objects with the second one.

So,

This one takes:

= $O(n^2)$

And then the same manner compared again first with the second one, this takes.

= $O(n^2)$

Therefore the total complexity,

= Θ(n2)
