PYTHON1.)Assume that price is an integer variable whose value is the price (in US currency) in cents of an item. Write a stateme

nt that prints the value of price in the form "X dollars and Y cents" on a line by itself. So, if the value of price was 4321, your code would print "43 dollars and 21 cents". If the value was 501 it would print "5 dollars and 1 cents". If the value was 99 your code would print "0 dollars and 99 cents".2.)Write a statement that reads a floating point value from standard input into temperature.3.)Write a statement that reads a word from standard input into firstWord.

Answer:

#part 1

#read the amount

amount=int(input("enter the amount:"))

#find the dollars

doll=int(amount/100)

// find the cents

cent=amount%100

#print output

print("{} dollars and {} cents.".format(doll,cent))

#part 2

#read a floating point

temperature=float(input("enter the temperature:"))

#part 3

#read a word

firstWord=input("enter a word:")

Explanation:

In part 1, read amount and the find the dollars with the help of "/" operator. Then find the cents with "%" operator and print both.In part 2, read a point and cast it to float then assign it to variable "temperature".In part 3,Read a word and assign it to variable "firstWord".

Output:

enter the amount:4321

43 dollars and 21 cents.

enter the temperature:12.5

enter a word:hello

Explain why a document created by word processing software is stored as a binary file.​
Savatey [412]

Answer:

Refer below.

Explanation:

Binary DOC records regularly contain more content organizing data (just as contents and fix data) than some other document designs like Rich Text Format and Hypertext Markup Language, however are normally less broadly good.

The DOC documents made with Microsoft Word renditions contrast. Microsoft Word forms before Word 97 ("8.0") utilized an alternate organization from the OLE/CFBF-based Microsoft Word 97 – 2003.

In Microsoft Word 2007 and later, the binary document design was supplanted as the default position by the Office Open XML group, however Microsoft Word can in any case produce DOC records.

Given an array A of size N, and a number K. Task is to find out if it is possible to partition the array A into K contiguous sub
Dennis_Churaev [7]

Answer: First lets solve the Prerequisite part

Lets say we have an input array of N numbers {3,2,5,0,5}. We have to  find number of ways to divide this array into 3 contiguous parts having equal sum. So the output for the above input array will be 2 as there are 2 ways to divide the array. One is (3,2),(5),(0,5) and the other is (3,2),(5,0),(5).

Following are the steps to achieve the above outcome.

  • Let p and q point to the index of array such that sum of array elements from 0 to p-1 is equal to sum of array elements from p to q which is equal to the sum of array elements from q+1 to N-1.  
  • If we see the array we can tell that the sum of 3 contiguous parts is 5. So the condition would be that sum of all array elements should be equal to 5 or sum of each contiguous part is equal to sum of all array elements divided by 5.
  • Now create 2 arrays prefix and postfix of size of input array. Index p of prefix array carries sum of input array elements from index 0 to index p. Index q of postfix array carries sum of input array elements from index p to index N-1
  • Next move through prefix array suppose at the index p of prefix array : value of prefix array == (sum of all input array elements)/5.
  • Search the postfix array for p index found above. Search it starting from p+2 index. Increment the count variable by 1 when the value of postfix array =(sum of all input array elements)/5 and push that index of postfix array into a new array. Use searching algorithm on new array to calculate number of values in postfix array.

Now lets solve the main task

We have an array A of size N and a number K. where A[]= {1,6,3,4,7} N=5 and K=3. We have to find if its possible to partition A into 3 contiguous subarrays such that sum of elements in each subarray is the same. It is possible in this example. Here we have 3 partitions (1,6),(3,4),(7) and sum of each of subarrays is same (1+6) (3+4) (7) which is 7.

Following are the steps to achieve the above outcome.

  • In order create K contiguous subarrays where each subarray has equal sum, first check the condition that sum of all elements in the given array should be divisible by K. Lets name another array as arrsum that will be the size of array A. Traverse A from first to  last index and keep adding current element of A with previous value in arrsum. Example A contains (1,6,3,4,7} and arrsum has {1,7,10,14,21}
  • If the above condition holds, now check the condition that each subarray or partition has equal sum. Suppose we represent sum1 to sum of all element in given array and sum2 of sum of each partition then: sum2 = sum2 / K.
  • Compare arrsum to subarray, begining from index 0 and when it becomes equal to sum2 this means that end of one subarray is reached. Lets say index q is pointing to that subarray.
  • Now from q+1 index find p index in which following condition holds: (arrsum[p] - arrsum[q])=sum2
  • Continue the above step untill K contigous subarrays are found. This loop will break if, at some index, sum2 of any subarray gets greater than required sum2 (as we know that every contiguous subarray should contain equal sum).

A easier function Partition for this task:

int Partition(int A[], int N, int k) // A arra y of size N and number k

{      int sum = 0;    int count = 0;  //variables initialization    

   for(int j = 0; j < N; j++)  //Loop that calculates sum of A

  sum = sum + A[j];        

  if(sum % k != 0) //checks condition that sum of all elements of A should be //divisible by k

   return 0;        

   sum = sum / k;  

   int sum2 = 0;  //represents sum of subarray

  for(int j = 0; j < N; j++) // Loop on subarrays

  {      sum2=sum2 + A[j];  

   if(sum2 == sum)    { //these lines locates subarrays and sum of elements //of subarrays should be equal

       sum2 = 0;  

       count++;  }  }  

/*calculate count of subarrays whose

sum is equal to (sum of complete array/ k.)

if count == k print Yes else print No*/

if(count == k)    

return 1;  

   else

   return 0;  }

Consider a physical transmission medium of capacity C bits/sec between two stations that have I bits of information sent/receive
levacccp [35]

Answer:

Check the explanation

Explanation:

when calculating the total time to send the I bits of information or The packet delivery time or latency which can be said to be the amount of time from when the first bit leaves the point of transmission until the last is received. When it comes to a physical link, it can be computed or determined as: Packet delivery time = Transmission time + Propagation delay.
