- Palindrome Checkercreate a JavaScript program that checks if phrasesentered by the user are palindromes. 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. Ask the user for the word and then read their input. To verify that their input string has been read correctly, test this by displaying…Alternate Character DisplayWrite a method that accepts a String object as an argument and then returns the alternate characters as substring starting from index 0. For instance, if the string argument passed is “GREAT”, the method should return “GET”. Demonstrate the method in a program that asks the user to input a string and then passes it to the method.Scanner method --------------- reads characters until it encounters a newline character, then returns those characters as a String.
- 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 }PART E: ROTATE LEFTGiven a string str, print out a rotated left 2 version where the first 2 chars are moved to the end. Assume thestring length will be at least 2.Methods to use: substring(), length(), concat()Testing cases: Hello => lloHe java => vaja Hi => Hi code => deco cat => tca 12345 => 34512 Chocolate => ocolateCh bricks => icksbThe __________ of a string object allow you to search for substrings.
- String.ParseInt(m); will convert the integer value of m to a String True Falsec programing languge Write a code that will do the following in order: 1- Take two strings from the user: s1 and s2 2- Compare the two strings and concatenate them such that the alphabetically first one goes first: Ex: Run 1: s1: Amy s2: Bruder Result: Amy Bruder Run 2: s1: Baby s2: Ahoy Result: Ahoy BabyTrue or FalseWhen you call a string object’s Split method, the method divides the string into two substrings and returns them as an array of strings.
- in c language Write a program which performs the following actions: Write the header of the C program Write the beginning of the main function Initialize a string called first_string with the constant value "C programming is nice**" using a string pointers Initialize a string called second_string with the constant value "C language is difficult" using a string pointer Display first_string and second_string in two consecutive lines Display a message that shows if the two strings have the same length (hint: use sizeof). Assume now that both strings have the same size. Write only three statements to swap the two strings’ contents (swap means the content of the first string becomes the content of the second string and vice-versa) Display again the two strings to check whether they have been swapped Write the correct symbol to close the main functionA string object's can be used to retrieve a specific collection of characters. derived from a stringstring = 'chegg' for c in string [::-1]: print (c, end = "") string = string.upper () a) CHEGG b) ggehc c) GEHC d) g
