Write a program to swap the first letter of a word with the first letter of the next word, for each of the word in a given string. Assume that the string starts and ends with a letter, has no punctuation marks and has exactly one space between two words. Also assume that there are even number of words in the string.

s = 'hello world';

Wanted = swap(s) % function call

% function

function Wanted = swap(str)

S = regexp(str,'\S*','match');

S([1,end]) = S([end,1]);

Wanted = strjoin(S);

end

or better still

% Create sample string.

str = 'one two three four five';

% Split apart into individual words without spaces.

words = strsplit(str)

% Swap the first and last words.

[words(end), words(1)] = deal(words(1), words(end))

% String the words together with spaces between them.

outputString = ''; % Initialize output

for k = 1 : length(words)

outputString = sprintf('%s ', outputString, words{k});

end

% Trim off the leading and trailing spaces.

outputString = strtrim(outputString)

Explanation:

all codes are written in matlab programming language.

// Scanner class is imported to allow program

// receive user input

import java.util.Scanner;

// class Solution is defined

public class Solution {

// main method that begin program execution

public static void main(String args[]) {

// Scanner object scan is defined

// to receive input via the keyboard

Scanner scan = new Scanner(System.in);

// prompt is display to user to enter two word

System.out.println("Enter your two-word: ");

// user input is assigned to user_input

String user_input = scan.next();

// user_input is splitted using space as separator

String[] splitted_input = user_input.split(" ");

// first word from the array is assigned to first_word

String first_word = splitted_input[0];

// second word from the array is assigned to second_word

String second_word = splitted_input[1];

// first character of first_word is assigned to temp

char temp = first_word.charAt(0);

// new_first_word is form by concatenating first character of second_word

// and substring of first_word

String new_first_word = second_word.charAt(0) + first_word.substring(1);

//new_second_word is form by concatenating the temp and

// substring of second_word

String new_second_word = temp + second_word.substring(1);

// the new words are displayed to the user

System.out.println("The new word is: \n" + new_first_word + " " + new_second_word);

}

}

Explanation:

The code is written in Java and well commented.

because they are scammers. our phones tells us when there are known scammers calling just so we can be informed. so basically they want to scam you. lol
