Write a recursive function that returns 1 if an array of size n is in sorted order and 0 otherwise. Note: If array a stores 3, 6

galina1969 [7]

Answer:

The function in C++ is as follows:

int isSorted(int ar[], int n){

if ( $n == 1$ || $n == 0$ ){

return 1;}

if ( $ar[n - 1]$ < $ar[n - 2]$ ){

return 0;}

return isSorted(ar, n - 1);}

Explanation:

This defines the function

int isSorted(int ar[], int n){

This represents the base case; n = 1 or 0 will return 1 (i.e. the array is sorted)

if ( $n == 1$ || $n == 0$ ){

return 1;}

This checks if the current element is less than the previous array element; If yes, the array is not sorted

if ( $ar[n - 1]$ < $ar[n - 2]$ ){

return 0;}

This calls the function, recursively

return isSorted(ar, n - 1);

}

Create a cell reference in a format by typing in the cell name or

Neko [114]

Answer:

D. Create a cell reference in a formula by typing in the cell name or clicking the cell.

Further Explanation:

To create a cell reference in a formula the following procedure is used:

First, click on the cell where you want to add formula.

After that, in the formula bar assign the equal (=) sign.

Now, you have two options to reference one or more cells. Select a cell or range of cells that you want to reference. You can color code the cell references and borders to make it easier to work with it. Here, you can expand the cell selection or corner of the border.

Again, now define the name by typing in the cell and press F3 key to select the paste name box.

Finally, create a reference in any formula by pressing Ctrl+Shift+Enter.

When TCP/IP translates a network layer address into a data link layer address, it sends a special ____________ to all computers

Llana [10]

Answer:

Broadcast message

Explanation:

The network models like OSI and TCP/IP suites have standard layers and protocols that governs the communication of end devices in a network.

The TCP/IP suite model has four layers which are application, transport, internet and network access layers. The network access does the work of both the data-link and physical layer of the OSI model.

When the packet is encapsulated in a data-link header and trailer, and needs to be sent to another unknown host, a broadcast message is sent to all the computers in the network to retrieve the remote host address for a unicast transmission to take place.
