Suppose you have two arrays of ints, arr1 and arr2, each containing ints that are sorted in ascending order. Write a static meth

telo118 [61]

Since both arrays are already sorted, that means that the first int of one of the arrays will be smaller than all the ints that come after it in the same array. We also know that if the first int of arr1 is smaller than the first int of arr2, then by the same logic, the first int of arr1 is smaller than all the ints in arr2 since arr2 is also sorted.

public static int[] merge(int[] arr1, int[] arr2) {
int i = 0; //current index of arr1
int j = 0; //current index of arr2
int[] result = new int[arr1.length+arr2.length]
while(i < arr1.length && j < arr2.length) {
result[i+j] = Math.min(arr1[i], arr2[j]);
if(arr1[i] < arr2[j]) {
i++;
} else {
j++;
}
}
boolean isArr1 = i+1 < arr1.length;
for(int index = isArr1 ? i : j; index < isArr1 ? arr1.length : arr2.length; index++) {
result[i+j+index] = isArr1 ? arr1[index] : arr2[index]
}
return result;
}

So this implementation is kind of confusing, but it's the first way I thought to do it so I ran with it. There is probably an easier way, but that's the beauty of programming.

A quick explanation:

We first loop through the arrays comparing the first elements of each array, adding whichever is the smallest to the result array. Each time we do so, we increment the index value (i or j) for the array that had the smaller number. Now the next time we are comparing the NEXT element in that array to the PREVIOUS element of the other array. We do this until we reach the end of either arr1 or arr2 so that we don't get an out of bounds exception.

The second step in our method is to tack on the remaining integers to the resulting array. We need to do this because when we reach the end of one array, there will still be at least one more integer in the other array. The boolean isArr1 is telling us whether arr1 is the array with leftovers. If so, we loop through the remaining indices of arr1 and add them to the result. Otherwise, we do the same for arr2. All of this is done using ternary operations to determine which array to use, but if we wanted to we could split the code into two for loops using an if statement.

An ellipse (three dots) following a menu item indicates that

Mariulka [41]

Answer:

Correct answer is

clicking on item will display a dailogbox/ more options

Explanation:

In web site menus have limited space.To add all items menus are grouped in categories and only category names are shown while there subsets are displayed in a drop down list upon hovering on them.

Some time designer user three dot indication which indicates there are more options available in a hidden side bar or dialog menu which opens upon clicking the ellipse.

Point out the wrong statement :

hoa [83]

Answer:

d. None of the mentioned

Explanation:

Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.

Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.

Cloud computing comprises of three (3) service models and these are;

1. Platform as a Service (PaaS).

2. Infrastructure as a Service (IaaS).

3. Software as a Service (SaaS).

All of the following statements are true and correct because they are standard internet protocols;

I. Virtual appliances are becoming a very important standard cloud computing deployment object. This depicts the Platform as a Service (PaaS).

II. Cloud computing requires some standard protocols.

III. Cloud computing relies on a set of protocols needed to manage interprocess communications.

Words or names defined by the programmer are called

polet [3.4K]

Words or names defined by the programmers are called as programmer defined symbols or identifiers. These are called as variables which are just simple storage locations and making available for the program to use. No two variables are same in the code of the program.
