Explanation:
Two character strings may have many common substrings. Substrings are required to be contiguous in the original string. For example, photograph and tomography have several common substrings of length one (i.e., single letters), and common substrings ph, to, and ograph as well as all the substrings of ograph. The maximum common substring length is 6. Let X = X122 . Im and Y = yıy2 - - • Yn be two character strings. Using dynamic programming, design an algorithm to find the maximum common substring length for X and Y using dynamic programming. Please follow the general steps for designing a dynamic programming solution as in Q1 (other than the actual programming part).
Answer:
Explanation:
The following function is written in Java. It takes two strings as parameters and calculates the longest substring between both of them and returns that substring length.
import java.util.*;
class Test
{
public static void main(String[] args)
{
String X = "photograph";
String Y = "tomography";
System.out.println(X + '\n' + Y);
System.out.println("Longest common substring length: " + longestSub(X, Y));
}
static int longestSub(String X, String Y)
{
char[] word1 = X.toCharArray();
char[] word2 = Y.toCharArray();
int length1 = X.length();
int length2 = Y.length();
int substringArray[][] = new int[length1 + 1][length2 + 1];
int longestSubstringLength = 0;
for (int i = 0; i <= length1; i++)
{
for (int j = 0; j <= length2; j++)
{
if (i == 0 || j == 0)
substringArray[i][j] = 0;
else if (word1[i - 1] == word2[j - 1])
{
substringArray[i][j]
= substringArray[i - 1][j - 1] + 1;
longestSubstringLength = Integer.max(longestSubstringLength,
substringArray[i][j]);
}
else
substringArray[i][j] = 0;
}
}
return longestSubstringLength;

Assume that class BankAccount exists, and that it has a constructor that sets the private field balance, and that setBalance and getBalance are defined by class BankAccount and set and get double values. Then what is the output of the following code:________.
a. 600.0
b. 0.0
c. 300.0
d. null
e. an error will result
Assume that class BankAccount exists, and that it has a constructor that sets the private field balance, and that setBalance and getBalance are defined by class BankAccount and set and get double values.
Then what is the output of the following code?
BankAccount b1 = new BankAccount(600.0);
BankAccount b2 = b1;
b1.setBalance(300.0);
System.out.println(b2.getBalance() );
Answer:300.0
Explanation:The given snippet of code is as follows:
=======================================
BankAccount b1 = new BankAccount(600.0);
BankAccount b2 = b1;
b1.setBalance(300.0);
System.out.println(b2.getBalance() );
=======================================
Line 1: An object b1 of the BankAccount class is created which sets the value of its balance to 600.0
Line 2: A second object, b2, is created referencing or pointing to the first object, b1 in memory. It could also be interpreted to mean that a second object b2 is created from the exact copy of the first object, b1. This is called object cloning. This by implication means that all the fields (including the contents of the fields) of the first object b1, are copied to b2 which also means that when there's a change in b1, an update is made to b2 also. If a change is made to b2, b1 also gets updated.
Line 3: Object b1 is updated by setting the value of its balance field to 300.0 using the setBalance() method. This will also update the same field for the second object b2.
Line 4: The value of the balance field of object b2 is being printed to the console. Since the value has been updated in line 3 when that of b1 was updated, 300.0 will be printed to the console.

1.6.1: Type casting: Computing average owls per zoo.
Assign avg_owls with the average owls per zoo. Print avg_owls as an integer.
Sample output for inputs: 1 2 4
Average owls per zoo: 2
-------------------------------------------------------------------
Someone please explain what I am doing wrong?
Answer:
avg_owls=0.0
num_owls_zooA = int(input())
num_owls_zooB = int(input())
num_owls_zooC = int(input())
num_zoos = 3
avg_owls = (num_owls_zooA + num_owls_zooB + num_owls_zooC) / num_zoos
print('Average owls per zoo:', int(avg_owls))
Explanation:
There is a problem while you are trying the calculate the average owls per zoo.
As you may know, in order to calculate the average, you need to get the total number of owls in all the zoos, then divide it to the number of zoos. That is why you need to sum num_owls_zooA + num_owls_zooB + num_owls_zooC and divide the result by num_zoos
Be aware that the average is printed as integer value. That is why you need to cast the avg_owls to an int as int(avg_owls)
(main.c File)
Counting the character occurrences in a file
For this task you are asked to write a program that will open a file called “story.txt”
and count the number of occurrences of each letter from the alphabet in this file.
At the end your program will output the following report:
Number of occurrences for the alphabets:
a was used – times.
b was used – times.
c was used – times…. …and so, on
Assume the file contains only lower-case letters and for simplicity just a single
paragraph. Your program should keep a counter associated with each letter of the
alphabet (26 counters) [Hint: Use array]
Your program should also print a histogram of characters count by adding
a new function print Histogram (int counters []). This function receives the
counters from the previous task and instead of printing the number of times each
character was used, prints a histogram of the counters. An example histogram for
three letters is shown below) [Hint: Use the extended asci character 254]
Answer:
C code
Explanation:
#include <stdio.h>
void histrogram(int counters[])
{
int i,j;
int count;
for(i=0;i<26;i++)
{
count=counters[i];
printf("%c ",i+97);
for(j=0;j<count;j++)
{
printf("="); //= is used
}
printf("\n");
}
}
int main()
{
FILE* fp;
int i;
int arr[26];
char c;
int val;
// Open the file
fp = fopen("story.txt", "r");
if (fp == NULL) {
printf("Could not open file ");
return 0;
}
else
{
for(i=0;i<26;i++)
arr[i]=0;
for (c = getc(fp); c != EOF; c = getc(fp))
{
if(c>='a' && c<='z')
{
val = c-97;
//printf("%d ",val);
arr[val]++;
}
}
histrogram(arr);
}

A major advantage of direct mapped cache is its simplicity and ease of implementation. The main disadvantage of direct mapped cache is: a. it is more expensive than fully associative and set associative mapping. b. it has a greater access time than any other method. c. its performance is degraded if two or more blocks that map to the same location are used alternately. d. it does not allow the cache to store the tag that corresponds to the block currently residing in that cache location.

The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the fibonacci() method, which takes in an index, n, and returns the nth value in the sequence. Any negative index values should return -1.
Ex: If the input is: 7
the out put is :fibonacci(7) is 13
Note: Use recursion and DO NOT use any loops. // is this mean i don't have to use loops? for (int i = 1; i<= n; ++i)

if(n<0)
return -1;
if(n==0||n==1)

int startNum;
System.out.println("Enter your number: ");
startNum = scnr.nextInt();
System.out.println("fibonnaci(" + startNum + ") is " + fibonacci(startNum));
}
}
Recursions involve calling a function from the function itself, until a condition is met.
The required function, where comments are used to explain each line is as follows:
//This defines the function
public static int fibonacci(int n) {
//The function returns -1, if n is negative
if(n<0){
return -1;}
//The function returns the value of n, if n is 0 or 1
if(n==0||n==1){
return n;}
//If otherwise
else{
//The function returns the nth term of the Fibonacci series
return fibonacci(n-1)+fibonacci(n-2);
}
}
At the end of the program, the nth term of the Fibonacci series is printed.

Let's implement a classic algorithm: binary search on an array. Implement a class named BinarySearcher that provides one static method named search. search takes a SearchList as its first parameter and a Comparable as its second. If either parameter is null, or if the SearchList is empty, you should throw an IllegalArgumentException. SearchList is a provided class. It provides a get(int) method that returns the Comparable at that index, and a size method that returns the size of the SearchList. Those are the only two methods you should need! search returns a boolean indicating whether the passed value is located in the sorted SearchList. To search the sorted SearchList efficiently, implement the following algorithm: Examine the value in the middle of the current array (index (start + end) / 2) If the midpoint value is the value that we are looking for, return true If the value that we are looking for is greater than the midpoint value, adjust the current array to start at the midpoint if the value that we are looking for is less than the midpoint value, adjust the current array to end at the midpoint Continue until you find the value, or until the start reaches the end, at which point you can give up and return false This is a fun problem! Good luck! Keep in mind that every time you call SearchList.get that counts as one access, so you'll need to reduce unnecessary accesses to pass the test suite.
