ask 3. Remove white spaces and special symbols rogram asks user to input a string to remove white spaces and special symbols (dashes, commas and dots). User inputs a string (with several words) and program prints out the input string with thite spaces and special symbols. You may use Scan objects and loops. xample: nput a string to remove special symbols: hey, - i like may.

Q3: Write a complete program to read a string from the user at the runtime and check if it is palindrome (syetrical).
Why does the following pseudocode not perform as indicated in the comments? Explain the problem and correct the error in the pseudocode. // This program counts the characters in a stringDeclare String wordDeclare Integer indexDeclare Integer letters = 0// Get the input from the userDisplay "Enter a word."Input word// Count the characters in the stringFor index = 0 To length(word)Set count = count + 1End ForDisplay "That word contains ", count, " characters."
Hello...Its not correct...
PART A: HALF A STRINGGiven a string str of even length, print out the first half. Methods to use: substring(), length()Testing cases:WooHoo => WooHelloThere => Helloabcdef => abcab => a0123456789 => 01234kitten => kit(Note that the sample input test cases are shown before the “=>” and the expected output each test case isafter the “=>”. Your program should print out the expected output only, not the input.)PART B: WITHOUT ENDSGiven a string str, print out the string without the first and last char. Assume the string length is at least 2.Methods to use: substring(), length()Testing cases:Hello => ell java => av coding => odin code => od ab => (empty string)Chocolate! => hocolate kitten => itte woohoo => oohoPART C: COMBO STRINGGiven 2 strings, str1 and str2, print out a string of the form short+long+short, with the shorter string on theoutside and the longer string on the inside. Assume the strings will not be the same length, and that…
A string is a palindrome if it is identical forward and backward. For example "anna", "civic", "level" and "hannah" are all examples of palindromicwords. Write a program that reads a string from the user and uses a loop to determine whether or not it is a palindrome. Display the result, including a meaningful output message.
The loop below is intended to collect all characters that occur more than once in a given string. When you try it out with a string such as “Mississippi”, you will note that that letters that occur three or more times are collected more than once. Modify the loop so that each repeated letter is collected exactly once. For example, when s is “Mississippi”, result should be “si” and not “sissii” Only allowed to edit code in the /* Your code goes here */ portion. Thanks for the help!

Loops: Based on the following code segment: int val = 10; String s = String.format("%d", val - 5); while (val < 25) { s +=String.format(",%3d", val); val += 5; } System.out.println(s); Select the code using a for loop that produces identical output: String s = String.format("%d", val); for (int val = 10; val < 25; val + 5) { s += String.format(",%3d", val); } System.out.println(s); Strings = String.format("%d", 5); for (int val = 10; val <= 25; val += 5) { s +=String.format(",%3d", val); } System.out.println(s); String s = String.format("%d", 5); for (int val s += String.format(",%3d", val); } == 10; val < 25; val + 5) { System.out.println(s); None of these will produce the same output. String s = String.format("%d", 5); for (int val = 10, val < 25, val += 5) { s += String.format(",%3d", val); } System.out.println(s); Strings = String.format("%d", 5); for (int val = 10; val < 25; val += 5) { s +=String.format(",%3d", val); } System.out.println(s); String s = String.format("%d", 5); for…
The following loop will end when.. a =" while a!='xyz': a = input() a. the user inputs the string 'xyz' (without the apostrophes) b. the user inputs anything other than the string 'xyz' (with the apostrophes) c. the user inputs the string 'xyz' (with the apostrophes) d. the user inputs anything other than the string 'xyz' (without the apostrophes)
