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.
Answer:
Physical layer is the first layer of OSI model. The detail about physical layer and its parts is given below in explanation section.
Explanation:
The physical layer is the lowest and first layer of the Open Systems Interconnection Model (OSI). The physical layer is used for the transmission of data in bit forms. For transmission of data between devices, it uses the transmission medium that is either wired or wireless.
In the wired cable the component of the psychical layer include cable and connectors that are implemented for carrying data from one place to another or simply to transmit data between two connected devices. The wireless transmission medium is used to transmit data in the form of electromagnetic signals for carrying data into a stream of bits. Over past advancements in networking technologies, rapid growth has been seen in wireless data transmission and Wi-Fi and Bluetooth communication are few names of it.
Components/Parts of Psychical Layer
In the physical layer, the hardware components used it in are the network interface cards, connectors and interfaces, intermediate devices, modems, and cables to facilitate the transmission of data between devices or from source to destination.
- The network interface card (NIC)
NIC is a component installed in the computer to connect it to any available devices over the network.
- Connectors and Interfaces
Connectors and interfaces are used to connect cables that are being used for transmission of data from one source to another. The decision to choose connectors and interfaces depends on the type of cable. Typical examples are RJ-45, RJ-11, V.35, HDMI, etc.
Cables are the physical components of the physical layer that carry optic or electromagnetic signals for transmission of data from source to destination in the network.
The intermediate devices are hubs and repeaters etc. The functions of these devices are to amplify or generate the signal at the intermediate point in a network.
Answer:
The answer is "Clustering"
Explanation:
Clustering is a technique, which includes the Microsoft Windows and the coordination with an individual multi-PC's, that is mostly connected to the local area network, as a single platform.
- It is cheaper than one device.
- It enables you to greater machine performance and increases usability and reliability, that's why the answer to this question is "Clustering".
