Answer:

void reverse(char dest[], char source[], int size)

{

for(int i=0;i<size;i++)//using for loop.

{

dest[i]=source[i];//assigning each element of source array to dest array.

}

int s=0,e=size-1;//initializing two elements s with 0 and e with size -1.

while(s<e){

char t=des[s]; //SWAPPING

dest[s]=dest[e]; //SWAPPING

dest[e]=t; //SWAPPING

s++;

e--;

}

Explanation:

I have used while loop to reverse the array.I have initialize two integer variables s and e with 0 and size-1.Looping until s becomes greater than e.

It will work as follows:

first s=0 and e=0.

dest[0] will be swapped with dest[size-1]

then s=1 and e=size-2.

then des[1] will be swapped with dest[size-2]

and it will keep on going till s is less than e.

Write a program that asks the user for three strings. Then, print out whether the first string concatenated to the second string

ipn [44]

Answer:

import java.util.Scanner;

public class num5 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter The First String");

String str1 = in.next();

System.out.println("Enter The Second String");

String str2 = in.next();

System.out.println("Enter The Third String");

String str3 = in.next();

String oneAndTwo = str1+str2;

if(str3.equals(oneAndTwo)){

System.out.println(str1+" + "+str2+" is equal to "+str3+"!");

}

else

System.out.println(str1+" + "+str2+" is not equal to "+str3+"!");

}

Explanation:

Implemented in Using Java Programming Language
Import Scanner Class to prompt and receive users' input
Create three string variables and store the three values entered by the user (str1, str2 and str3)
Concatenate str1 and str2 using the + operator and assign to a new variable
Use the if statement with Java's .equals() method to check for equality of the new string with the third string
Print the appropriate message if the equal or not

Write a program whose inputs are two integers, and whose output is the smallest of the two values.

andrezito [222]

Method 1 :

Using If else statements: If the condition checks whether num1 is smaller than num2 if so it will print 'Smallest of these two integers is num1'.

else it will print 'Smallest of these two integers is num2'

Method 2:

Using the 'min' method: using the method min(num1,num2), the program finds the smallest value and prints it directly to the user.

Python Program using method 1

#PYTHON PROGRAM TO FIND SMALLEST INTEGER VALUE FROM TWO INPUTS FROM USER - Method 1

#Accepts inputs from user

num1 = int (input ("Enter your first number:")) #Gets the first integer input from user and stores in num1

num2 = int (input ("Enter your second number: ")) #Gets the second integer input from user and stores in num2

#Finding output by if else

#Checks num1 smaller than num2

if (num1 < num2):

#assign num1 to small

small = num1

else:

#assign num2 to small

small = num2

print ("Smallest of these two integers is", small)

Python Program using method 2

#PYTHON PROGRAM TO FIND SMALLEST INTEGER VALUE FROM TWO INPUTS FROM USER - Method 2

#Accepts inputs from user

num1 = int (input ("Enter your first number:")) #Gets the first integer input from user and stores in num1

num2 = int (input ("Enter your second number: ")) #Gets the second integer input from user and stores in num2

#Finding output using min method

print("\n Smallest of these two integers is",min(num1,num2)) #Prints output to user

Write a function called has_duplicates that takes a string parameter and returns True if the string has any repeated characters.

vichka [17]

Answer:

Explanation:

The python code for the question is attached in the image below.

The objective here is to write a code in python with a function called has_duplicates that takes a string parameter and returns True if the string has any repeated characters. Otherwise, it should return False.

SEE BELOW FOR THE CODE.

alphabet = "abcdefghijklmnopqrstuvwxyz"

test_dups = ["zzz","dog","bookkeeper","subdermatoglyphic","subdermatoglyphics"]

test_miss = ["zzz","subdermatoglyphic","the quick brown fox jumps over the lazy dog"]

def histogram(s):

d = dict()

for c in s:

if c not in d:

d[c]=1

else:

d[c] += 1

return d

def has_duplicates():

for string in test_dups:

dictionary=histogram(string)

duplicates=False

for ch in dictionary.keys():

if dictionary[ch] > 1:

duplicates=True

break

if duplicates==True:

print(string,"has duplicates")

else:

print(string,"has no duplicates")

def missing_letters(string):

answer=""

for ch in alphabet:

if ch not in string:

answer=answer+ch

return answer

print("__________________________________________")

print(" Calling has_duplicates() function")

print("__________________________________________")

has_duplicates()

print("\n______________________________________________")

print("Calling missing_letters() function in for loop")

print("______________________________________________")

for i in test_miss:

answer=missing_letters(i)

if len(answer)>=1:

print(i,"is missing letters",answer)

else:

print(i,"uses all the letters")
