Answer:

I am writing Python program.

string = input("Enter a string: ")

print(string.count(' '))

Explanation:

The first statement takes input string from the user.

input() is used to read the input from the user.

The next statement uses count() function to count the number of times the specified object which is space ' ' here occurs in the string.

The print() function is used to return the number of times the space occurs in the string entered by the user.

Output:

Enter a string: How are you doing today?

The screenshot of program and its output is attached.

Write a program FindDuplicate.java that reads n integer arguments from the command line into an integer array of length n, where

kozerog [31]

Answer:

public class FindDuplicate{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int n = 5;
int arr[] = new int[n];
for(int i=0; i < arr.length; i++){
int inputNum = input.nextInt();
if(inputNum >=1 && inputNum <=n) {
arr[i] = inputNum;
}
}
for(int j =0; j < arr.length; j++){
for(int k = 0; k < arr.length; k++){
if(j == k){
continue;
}else{
if(arr[j] == arr[k]){
System.out.println("True");
return;
}
}
}
}
System.out.println("False");
}
}

Explanation:

Firstly, create a Scanner object to get user input (Line 4).

Next, create an array with n-size (Line 7) and then create a for-loop to get user repeatedly enter an integer and assign the input value to the array (Line 9 - 14).

Next, create a double layer for-loop to check the each element in the array against the other elements to see if there is any duplication detected and display "True" (Line 21 - 22). If duplication is found the program will display True and terminate the whole program using return (Line 23). The condition set in Line 18 is to ensure the comparison is not between the same element.

If all the elements in the array are unique the if block (Line 21 - 23) won't run and it will proceed to Line 28 to display message "False".

Modify the guessing-game program so that the user thinks of a number that the computer must guess.

Triss [41]

Answer:

import random

import math

smaller = int(input("Enter the smaller number: "))

larger = int(input("Enter the larger number: "))

count = 0

print()

while True:

count += 1

myNumber = (smaller + larger) // 2

print('%d %d' % (smaller, larger))

print('Your number is %d' % myNumber)

choice = input('Enter =, <, or >: ')

if choice == '=':

print("Hooray, I've got it in %d tries" % count)

break

elif smaller == larger:

print("I'm out of guesses, and you cheated")

break

elif choice == '<':

larger = myNumber - 1

else:

smaller = myNumber + 1

Explanation:

The code to be Modified is as indicated below:

# Modify the code below:

import random

smaller = int(input("Enter the smaller number: "))

larger = int(input("Enter the larger number: "))

myNumber = random.randint(smaller, larger)

count = 0

while True:

count += 1

userNumber = int(input("Enter your guess: "))

if userNumber < myNumber:

print("Too small")

elif userNumber > myNumber:

print("Too large")

else:

print("You've got it in", count, "tries!")

break

Detailed Explanation:

Line 3 and 4 of the codes prompts the user to enter a smaller and larger number. Line 5 we initiate the formula for minimum number of guesses. Line 14 and 17 prints out the output I'm out of guesses, and you cheated and Hooray, I've got it in X after validating the conditions.

Consider an improved version of the Vigen ere cipher, where instead of using multiple shift ciphers, multiple mono-alphabetic su

anzhelika [568]

Answer:

Kasiski’s method for determining 't' works for Vigenère cipher as well. The only difference is therefore in the second stage of the attack. In the second stage, one needs to build a frequency table for each of the 't' keys, and carry out an attack like on the mono-alphabetic cipher. Given a long enough plaintext, this will work successfully.

Explanation:

Kasiski method is a method of attacking polyalphabetic substitution ciphers such as Vigenère cipher. It is also called Kasiski test or Kasiski examination.

The method involve finding the length of the keyword and then dividing the message into that many simple substitution cryptograms. Frequency analysis could then be used to solve the resulting simple substitution.
