Answer:

The answer to this question is "15 line".

Explanation:

A function is a block of ordered, portable code used to perform a single, connected operation. The syntax of function declaration can be given as:

Syntax :

returntype functionName(parameter1, parameter2); //function prototype

or declaration

returntype functionName(parameter1, parameter2) //function definition or header of the function  

{  

//function body.

//function implementation

 //return value;

}

In the given question the header of the showDub function is on line 15.

That's why the answer to this question is "15 line".

A complete traversal of an n node binary tree is a(n)____ "operation if visiting a node is O(1)for the iterative implementation
ch4aika [34]

Answer:

B.O(n).

Explanation:

Since the time complexity of visiting a node is O(1) in iterative implementation.So the time complexity of visiting every single node in binary tree is O(n).We can use level order traversal of a binary tree using a queue.Which can visit every node in O(n) time.Level order traversal do it in a single loop without doing any extra traversal.

What are five don’ts of using a computer
Sonja [21]

Answer:

well, as long as there are no right or wrong answers, don't:

look to closely at the screen, as it may mess up your eyes

hold a drink above the computer, as it may spill and cause "sticky keys"

go to sites that you know will give your a computer a virus, cause they cost hundreds of dollars to repair, and some aren't able to come out

go on illegal sites/do illegal operations to the computer itself, because then you won't have a computer

Write a bool function isPalindrome that takes one string parameter and returns true if that string is a palindrome and false oth
kkurt [141]

Answer:

Here is the bool function isPalindrome:

bool isPalindrome(string s)

{  bool palindrome;      

 int j;

 int len = s.length();

 for (int i =0, j= len-1; i < len/2; i++, j--)  

   if (s[i] == s[j])

     palindrome = true;  

   else

     palindrome = false;

 return palindrome; }

Explanation:

The bool function isPalindrome takes a string as parameter and returns true if the string is a palindrome or false if the string is not palindrome. The string variable s holds the string value. In function isPalindrome, there is a bool type variable palindrome. bool is a data type which is used to hold values true or false which is then stored in the palindrome variable.

Next it is being found that how many characters are there in the input string using length() function which returns the length of the string. The length of the string is stored in int type variable len.

Next the for loop starts which has two variables i and j where i starts at 0 position of the input string and j starts at the last position of the string. These two variables move or traverse along the string this way. i variable stops when half the length of the input string is reached. At the end of every iteration i moves forward by the increment of its value to 1 and j moves backwards by the decrement  of its value to 1.

Every the body of  the loop executes, there is an if condition in the body of the loop which checks if the string is a palindrome. This is checked by matching the character at position/index i with the character at position j of the string. This will continue character by character until the i reached half the length of the input string and if every character in i was matched to every character in j then palindrome = true; statement is executed which returns true as the string is a palindrome otherwise palindrome = false; is returned as the string is not a palindrome.

For taking input string from the user and to check if the function isPalindrome() works correctly a main() function is written which takes input string from the user and reads in variable str calls isPalindrome() function. If the string is palindrome then the cout statement in main() function prints the message: String is a palindrome and if the input string is not a palindrome the the following message is displayed in the output screen: String is not a palindrome

int main()

{

string str;

cout<<"Enter a string: ";

cin>>str;

if(isPalindrome(str))

cout<<"String is a palindrome";

else

cout<<"String is not a palindrome";

}

The screenshot of the program along with the output is attached.
