- public static String pancakeScramble(String text) This nifty little problem is taken from the excellent Wolfram Challenges problem site where you can also see examples of what the result should be for various arguments. Given a text string, construct a new string by reversing its first two characters, then reversing the first three characters of that, and so on, until the last round where you reverse your entire current string. This problem is an exercise in Java string manipulation. For some mysterious reason, the Java String type does not come with a reverse method. The canonical way to reverse a Java string str is to first convert it to mutable StringBuilder, reverse its contents, and convert the result back to an immutable string, that is, str = new StringBuilder(str).reverse().tostring(); A bit convoluted, but does what is needed without fuss or muss. Maybe one day the Java strings will come with the reverse method built in, just like the string data types of all sensible…arrow_forwardTopics: User-defined functions, list, string, docstringProblem Statement: This program finds the unique letters from a given string and printsthe unique letters and their count. For example: word ‘LITTLE’ has ‘L’, ‘I’, ‘T’, ‘E’ are theunique letters.Lab Scenario:The program repeats until hits ‘n’. The program takes a user input of a string. The programfinds the unique letters in the string, add them in a list and displays the list and their count.Consider the following important points:1) You need to design a user-defined function named count_unique_letters whichtakes user word as parameter and returns the list of unique letters calledunique_letters in the given word.a. Hint: Iterate over each letter in user word, check if the letter is in the list, if notadd it to the list, otherwise continue to the next letter. A ‘in’ keyword can helpto determine if a character in the unique_letters list.b. You need to write a simple docstring for this function.2) Your program must have a main()…arrow_forward?(ls empty string e L(G Yes Noarrow_forward
- def swap_text(text): Backstory: Luffy wants to organize a surprise party for his friend Zoro and he wants to send a message to his friends, but he wants to encrypt the message so that Zoro cannot easily read it. 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_forwardWrite a function that reverses a string. The header of the function is: def reverse(s):Write a test program that prompts the user to enter a string, invokes the reverse function, and displays the reversed string.arrow_forwardWrite a function that finds the number of occurrences of a specified character in a string using the following header:def count(s, ch):The str class has the count method. Implement your method without using the count method. For example, count("Welcome", 'e') returns 2. Write a test program that prompts the user to enter a string followed by a character and displays the number of occurrences of the character in the string.arrow_forward
- public String firstAndLast(String str) { //declare and create your first char //declare and create your second char //return your first and last char as a String }arrow_forwardQ5. (Find the second lowest interger number) Write a program that prompts the user to enter a set of integer numbers, and finally displays the second lowest integer number in the set. To exit from the program enter -1. Here is a sample run Enter a set of integer numbers: 3 57 928-1 The second lowest number is 3.arrow_forwardQ1:Write C code for a program that reads two positive integer number, checks whether these number are co-prime or not, and prints the result.Note: two numbers are co-prime numbers if they do not have a common factor other than 1. For example, 10 and 11 are co-prime.arrow_forward
- rin t] (Replace strings) Write the following function that replaces the occurrence of a substring old substring new_substring in the string s. The function returns true if string s is changed, and otherwise, it returns false. bool replace_strings(string& s, with new substring a const string& old_string, const string& new_string) Write a test program that prompts the user to enter three strings, i.e., s, old_string, and new_string, and display the replaced string.arrow_forwardQ7: (Find the second lowest integer number) Write a program that prompts the user to enter a set of integer numbers, and finally displays the second lowest integer number in the set. To exit from the program enter -1. Here is a sample run Enter a set of integer numbers: 3 5 7 9 2 8 -1 The second lowest number is 3arrow_forwardpython: a function that counts the number of occurrences of given character in a given string. For example, calling the function with Count(‘j’, ‘just joshin’) returns 2. Note the function counts the character regardless of case.arrow_forward
