python Consider this data sequence: "3 11 5 5 5 2 4 6 6 7 3 -8". Any value that is the same as the immediately preceding value i

s considered a CONSECUTIVE DUPLICATE. In this example, there are three such consecutive duplicates: the 2nd and 3rd 5s and the second 6. Note that the last 3 is not a consecutive duplicate because it was preceded by a 7. Write some code that uses a loop to read such a sequence of non-negative integers, terminated by a negative number. When the code finishes executing, the number of consecutive duplicates encountered is printed. In this case,3 would be printed. ASSUME the availability of a variable, stdin, that references a Scanner object associated with standard input.

int firstNumber,secondNumber = -1, duplicates = 0;

do {

secondNumber = firstNumber;

}else {

if ( secondNumber == firstNumber )

else

secondNumber = firstNumber;

}

} while(firstNumber > 0 );

cout << duplicates;

disa [49]

Answer:

Following are the code to this question:

def combine_guest(guest1, guest2):#defining a method combine_guest that accepts two dictionary

   guest2.update (guest1)#use dictionary guest2 that use update method to update guest2 dictionary

   return guest2#return guest2 dictionary values

Rory_guest= { "Ada":2, "Ben":3, "Dav":1, "Jo":3, "Charry":2, "Terry":1, "bob":4}#defining a dictionary and add value

Taylor_guest = { "Dav":4, "Nan":1, "bobert":2, "Ada":1, "Samantha":3, "Chr":5}#defining a dictionary and add value

print(combine_guest(Rory_guest,Taylor_guest))#calling the combine_guest method

Output:

{'Nan': 1, 'Samantha': 3, 'Ada': 2, 'bob': 4, 'Terry': 1, 'Jo': 3, 'Ben': 3, 'Dav': 1, 'Charry': 2, 'bobert': 2, 'Chr': 5}

Explanation:

In the code a method, "combine_guest" is defined, that accepts two dictionaries "guest1, guest2" inside the method, in which the "guest2" dictionary uses the update method to combine the value of the guest1 dictionary and use a return keyword to return guest2 values.

In the next step, two dictionaries are declared, that holds some values and use a print method to call the "combine_guest" method and prints its return values.

Write a loop that subtracts 1 from each element in lowerScores. If the element was already 0 or negative, assign 0 to the elemen
Xelga [282]

Answer:

The JAVA program to implement for loop for given scenario is shown below.

public class MyProgram {

   public static void main(String args[]) {    

     int len = 5;

     int[] lowerScores = new int[len];      

     lowerScores[0] = 5;

     lowerScores[1] = 0;

     lowerScores[2] = 2;

     lowerScores[3] = -3;      

     System.out.println("The original elements of array are ");

     for(int i=0; i<len; i++)

     {

         System.out.print(lowerScores[i]+" ");

     }      

     System.out.println();

     System.out.println("The modified elements of array are ");

     for(int i=0; i<len; i++)

     {

         // if element is 0 or negative, 0 is assigned to this index

         if(lowerScores[i] <= 0)

           lowerScores[i] = 0;

       // 1 is subtracted from every non zero and positive element

         else

           lowerScores[i] = lowerScores[i] - 1;

           

       System.out.print(lowerScores[i]+" ");

     }

   }

}

OUTPUT

The original elements of array are  

5 0 2 -3 0  

The modified elements of array are  

4 0 1 0 0

Explanation:

The integer array is declared as shown.

int[] lowerScores = new int[len];

The length of the array is given by integer variable len. As per the question, we have taken four elements and size of 5 for the given array.

int len = 5;

The elements of the array are initialized inside the program with the elements given in the question.

lowerScores[0] = 5;

      lowerScores[1] = 0;

The values of the array can be changed to test the program. Also, the size of the array can be changed for testing.

As per the given scenario, if the element is greater than zero, 1 is subtracted from this element. For elements less than or equal to zero, that particular element is assigned the value of 0.

The given program implements if else statement inside for loop for this purpose.

for(int i=0; i<len; i++)

     {

         // if element is 0 or negative, 0 is assigned to this index

         if(lowerScores[i] <= 0)

           lowerScores[i] = 0;

       // 1 is subtracted from every non zero and positive element

         else

           lowerScores[i] = lowerScores[i] - 1;

     }
