Chapter 9, Problem 4FTE
Explanation of Solution
Given statements:
//Tokenize a string that is delimited
//with semicolons. The string has 3 tokens
String str = "one;two;three"; //Line 1
String tokens = str.split(";"); //Line 2
System.out.println(tokens); //Line 3
Error in the given statement:
Tokenizing string:
- It is a process of breaking down the string into the components called tokens.
- The string can be split using the split method which breaks the string using the delimiter for breaking it.
- The split method is used for the tokenizing the string.
Error #1:
The “tokens” variable must reference the array of tokens that is returned by the method “split ()” in “Line 2”. So the statement must be rewritten as:
String[] tokens = str...

The message is encrypted by exchanging pairs of characters. Description: This function gets a text (string) and creates a new text by swapping each pair of characters, and returns a string with the modified text. For example, suppose the text has 6 characters, then it swaps the first with the second, the third with the fourth and the fifth with the sixth character. Parameters: text is a string (its length could be 0)Return value: A string that is generated by swapping pairs of characters. Note that if the Examples: swap_text ("hello") swap_text ("Party for Zoro!") swap_text ("") def which_day(numbers): → 'ehllo'→ 'aPtr yof roZor!' → '' length of the text is odd, the last character remains in the same position.arrow_forwardint main(){ string str; int count = 0; // user input cout << "Enter string: "; cin >> str; int n = str.length(); // iterating over the string for (int i = 0; i < n - 1; i++) { // calling the fucntion to find the palidrome strings from the user input if (isPalindrome(0, i, str) && isPalindrome(i + 1, n - 1, str)) { // if 2 substring are palindrome then print them and increment count for (int x = 0; x < i + 1; x++) cout << str[x]; cout << " "; for (int x = i + 1; x < n; x++) cout << str[x]; count++; // break the loop after printing the palindrom string break; } } // if count is 0 then no palindrome subtring pair found if (count == 0) cout << "NO";} change this code to stdio.h string.harrow_forward

A palindrome is a word, number, phrase, or other sequence of characters which reads the same backward as forward, such as “SIR”,“raceBIKE”, “Never odd or even”, “20/1/20”. The program should prompt the user to typein a phrase that is at least three characters long, and then tell the user whether the phrasewas a palindrome. Note, the decision should be based solely on letters and numericaldigits, and so it should not consider other characters, such as spaces or exclamationmarks, even though these might be entered by the user. when checking palindromes.A. Select your test data with care. Both palindromes and non-palindromes would be included in this. Provide examples that are text, numeric, and mixed; ignore any additional characters and spaces; andB.
