Primary storage is usually termed as the viotile storage unit directly accessible as the main device to the CPU. So the main form of primary storage is RAM. It is the main storage unit where you keep your long term memory for your computer
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.

Explanation:
Computers help increase user productivity, and users become more productive at everything you do on the software running on the computer with a good understanding. For instance, when you have work on an Excel worksheet with a basic understanding, you can create, edit, delete, store, calculation, and print documents and letters. With all pre-existing technologies, all of these things were either impossible or much slower.One of the most useful advantages of computers is able to store and access vast amounts of data, which can be retrieved in the future. For example, a computer system and devices like eBook readers have enough storage capacity as they can store hundreds or thousands of books. Also, you can store movies, pictures, songs digitally, and documents on the computer, and can quickly find data accordingly and share information between devices. It reduces plastics and paper requirements that are used to make non-digital versions of the media.A computer has the ability to connect you to the network or the Internet. Once you connected, you can search for any type of information and can download audio, video, movies, documents, and more.Computers help you to connect with your friend, family, or other relatives with long-distance through e-mail and social networking.
